P\u0159ehled produktu<\/h2>\n

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<\/strong> 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.<\/p>\n

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.<\/p>\n

The T1-T10 Lineup at a Glance<\/h3>\n

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.<\/p>\n

Torque Rating Table by Series<\/h2>\n

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.<\/p>\n

Understanding the Part Numbering System<\/h2>\n

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:<\/p>\n

\n\n\n\n\n\n\n\n\n\n
Code Position<\/th>\nWhat It Tells You<\/th>\nExample<\/th>\n<\/tr>\n
Tube type prefix<\/td>\nT = Triangular, L = Lemon, ST = Star, G = Spline<\/td>\nT<\/td>\n<\/tr>\n
Series number<\/td>\nCross-kit size and torque class<\/td>\n6 (= T6 series)<\/td>\n<\/tr>\n
Color code<\/td>\nYB = Yellow+Black, etc.<\/td>\nYB<\/td>\n<\/tr>\n
Shield structure code<\/td>\nSafety shield type and bearing style<\/td>\nYIIIP<\/td>\n<\/tr>\n
Yoke codes<\/td>\nTractor-end and implement-end yoke types<\/td>\n05B (push pin spline)<\/td>\n<\/tr>\n
Overall length<\/td>\nMinimum closed length in mm<\/td>\n900<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

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.<\/p>\n

Available Tube Profiles Across the Range<\/h2>\n

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 zem\u011bd\u011blsk\u00fd v\u00fdvodov\u00fd h\u0159\u00eddel<\/a> buyer:<\/p>\n

\n
\n

Triangular (T)<\/p>\n

General-purpose farming. Best all-around choice for most Korean operations. Easy to assemble in cold weather due to self-centering shape.<\/p>\n<\/div>\n

\n

Lemon (L)<\/p>\n

Moderate angular tolerance. Popular on disc mowers and implements that require some flex at the tube joint during operation.<\/p>\n<\/div>\n

\n

Star (ST)<\/p>\n

Higher torque capacity per unit diameter. Used for heavy-duty applications above 80 HP where triangular tubes would be undersized.<\/p>\n<\/div>\n

\n

Hexagonal (G)<\/p>\n

Six-sided spline profile for industrial and marine applications. Maximum torque transfer with minimal angular flexibility.<\/p>\n<\/div>\n<\/div>\n

Selecting the Right T-Series Model<\/h2>\n

Choosing from the T1-T10 range comes down to three decisions. Get these right and you’ll have a hnac\u00ed h\u0159\u00eddel PTO<\/strong> that fits your equipment precisely:<\/p>\n

Match Torque to Your Tractor HP<\/h3>\n

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.<\/p>\n

Confirm Your Spline Interface<\/h3>\n

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.<\/p>\n

Measure Closed Length<\/h3>\n

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.<\/p>\n

How T-Series Shafts Connect to Gearboxes<\/h3>\n

The T Series PTO Drive Shaft Triangular Tube delivers rotation to the zem\u011bd\u011blsk\u00e1 p\u0159evodovka<\/a> 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.<\/p>\n

Parts and Accessories<\/h3>\n

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.<\/p>\n
