Eixo de acionamento da tomada de força série T com tubo triangular | T1-T10

Visão geral do produto

The letter "T" in this product line stands for triangular, referring to the three-sided cross-section of the telescoping tubes. The T Series PTO Drive Shaft Triangular Tube is the broadest product family in our catalog, spanning ten distinct series (T1 through T10) that cover virtually every horsepower class used in Korean agriculture. Whether you're connecting a 15 HP compact Kubota to a bed former or linking a 120 HP row-crop tractor to a heavy rotary cutter, one of the T1-T10 models matches your torque and length requirements.

What makes this range practical for Korean equipment dealers and cooperatives is standardization. All ten series share the same yoke attachment types, safety shield design, and grease fitting layout. The only variables are tube dimensions, cross-bearing size, and torque rating. That means a mechanic who knows how to service a T3 can service a T8 without relearning anything.

 

The T1-T10 Lineup at a Glance

Each step up in series number brings a larger tube diameter, bigger cross-bearing kit, and higher torque capacity. The T Series PTO Drive Shaft Triangular Tube selection starts with T1 for sub-compact tractors and scales to T10 for mid-range industrial use. Most Korean farm operations fall within the T3 to T7 range, which covers 25 HP through 80 HP applications.

Torque Rating Table by Series

The table below shows the torque capacity of each T Series PTO Drive Shaft Triangular Tube at both 540 and 1000 RPM PTO speeds. MP(NM) indicates the maximum permissible torque in Newton-meters. Always select a series rated above your tractor's actual PTO torque output to maintain a safety margin.

General Specifications

These parameters apply across the entire T Series PTO Drive Shaft Triangular Tube family. Individual series differ in tube diameter and cross-bearing size, but the materials, processing methods, and quality certifications are shared.

Understanding the Part Numbering System

Every T Series PTO Drive Shaft Triangular Tube uses a structured part number that tells you exactly what's inside the assembly. Once you learn the code, you can decode any T-series shaft specification at a glance. Here's how the system works:

So a part number like "T6 900 05B05B YIIIP" tells you: T6 series triangular shaft, 900 mm closed length, push-pin spline yokes on both ends, standard safety shield configuration. Our Korean support team uses this code system when helping you specify the right T Series PTO Drive Shaft Triangular Tube for your equipment.

Available Tube Profiles Across the Range

While the "T" designation specifically refers to triangular tubes, the same series framework supports other tube profiles for applications where triangular isn't the best fit. Here's how the profiles compare for an eixo de tomada de força agrícola buyer:

Selecting the Right T-Series Model

Choosing from the T1-T10 range comes down to three decisions. Get these right and you'll have a eixo de acionamento da tomada de força that fits your equipment precisely:

Match Torque to Your Tractor HP

Calculate your PTO torque using the formula: Torque (Nm) = Power (kW) x 9549 / RPM. Then select a T-series with an MP rating at least 30% above your calculated figure. For a 50 HP tractor at 540 RPM, that's about 660 Nm continuous, so a T4 (MP 780 Nm) or T5 (MP 1050 Nm) would be appropriate choices.

Confirm Your Spline Interface

Count the splines on both the tractor PTO stub and the implement input shaft. The T Series PTO Drive Shaft Triangular Tube supports all common configurations: 1-3/8" Z6, 1-3/8" Z21, 1-3/4" Z20, 1-3/4" Z6, and metric 8-spline options for Japanese tractors used across Korea.

Measure Closed Length

With implement lowered, measure yoke-face to yoke-face. Then raise to transport height and measure again. The T Series PTO Drive Shaft Triangular Tube must telescope across that entire range with at least 150 mm of overlap remaining at maximum extension. We offer custom lengths on request.

How T-Series Shafts Connect to Gearboxes

The T Series PTO Drive Shaft Triangular Tube delivers rotation to the caixa de engrenagens agrícola on your implement. The gearbox converts the PTO speed and direction to match the working mechanism's needs. A rotary tiller gearbox reduces 540 RPM to 200-300 RPM at the blade shaft while proportionally increasing torque. Both the shaft's implement-end yoke spline and the gearbox input spline must match for proper engagement.

Parts and Accessories

Triangular tube pairs, cross-bearing kits, yokes in all attachment styles, safety shields, torque limiters (SA, SB, SFF, RA types), and wide-angle joint (WA/CV) upgrades are all compatible with the T Series. Order individual parts for repair or a complete assembly for new installations.

Why the T-Series Is Korea's Best-Selling PTO Shaft

• ▶ Ten series levels from T1 to T10 cover every HP class from compact to mid-range industrial
• ▶ Standardized yoke, shield, and grease fitting design across all ten series simplifies maintenance
• ▶ Published torque ratings (172 Nm to 1050+ Nm) let you size with confidence, not guesswork
• ▶ Triangular tubes are the most stocked profile in Korea, meaning fast availability
• ▶ Full compatibility with SA, RA, SB, SFF torque limiters and WA/CV wide-angle joints
• ▶ CE, ISO 9001, TS/16949 certified with batch-traceable production records
• ▶ 30 to 45 percent below OEM pricing for equivalent T-series specifications

Perguntas frequentes

Which T-series do I need for a 45 HP tractor?

For 45 HP at 540 RPM, the continuous torque is about 590 Nm. A T4 (MP 780 Nm) provides a comfortable safety margin. If you anticipate heavy shock loads (rocky soil tillage), step up to a T5.

Can I use a T-series shaft at 1000 RPM?

Yes. Refer to the 1000 RPM column in the torque table. The torque capacity is slightly lower at 1000 RPM because the cross-bearings experience more rotational cycles. Select a 21-spline yoke for 1000 RPM PTO stubs.

What's the difference between T-series and L-series besides tube shape?

The T Series PTO Drive Shaft Triangular Tube has slightly higher torque capacity per tube diameter due to the flat-face contact geometry. The L-series lemon profile offers better angular tolerance at the tube joint. For most general farming, either works. Choose based on your implement's angular requirements.

Can I add a torque limiter to a T-series shaft?

Yes. All T-series models accept SA (ratchet), SB (shear bolt), SFF (friction), and RA (overrunning) limiters as factory-installed options. The limiter code appears in the part number suffix.

Are custom closed lengths available for the T-series?

Yes. Send us the yoke-to-yoke measurement at both working height and transport height. We cut the triangular tubes to your specification within 10 business days, no minimum order.

How do I grease the T Series PTO Drive Shaft Triangular Tube?

Cross-bearing grease fittings every 8 operating hours using NLGI #2 EP grease. Triangular tube overlap zone every 50 hours (clean old grease first). Same procedure across all T1-T10 models.

Ahn Byung-chul, Agricultural Cooperative Manager, Chungcheongbuk-do (spring 2025)

"Our cooperative standardized on the T-series three years ago for all shared tractors. We run T3 through T6 across different HP classes. Maintenance is simple because the greasing layout is identical across all models. When a member needs a replacement, I just match the series number to their tractor HP and order."

Yoo Hae-in, Rice Equipment Dealer, Iksan (late 2024)

"T4 and T5 are my two best-selling models. They cover the 35 to 60 HP range that most Jeolla-do rice farmers operate in. I keep eight of each in stock and they move every planting and harvest season. Quality is reliable, customer complaints are nearly zero."

Park Seon-ah, Greenhouse Operator, Gyeonggi-do (early 2025)

"T2 series for my 20 HP compact tractor running a bed former. Small, light, does the job without any fuss. The triangular tube slides smoothly and the push pin yoke lets me disconnect in seconds when I need to switch to the sprayer."

Nam Ki-tae, Municipal Parks Department, Daejeon (mid 2024)

"We run T6 models on 70 HP tractors with rotary mowers for park and roadside maintenance. The torque rating matches our needs with headroom to spare. After a full mowing season on each unit, the cross-bearings still feel tight and the tubes telescope cleanly."

Lim Dong-su, Yanmar Tractor Service, Busan (fall 2024)

"I service Yanmar tractors with metric PTO stubs. Finding T-series shafts with the 8-spline 38x32mm yoke used to mean special ordering from Japan. Ever-Power stocks them in Korea. That alone earned my business."
