TCC-IV Long Travel Constant Contact Side Bearings

Basic information

The characteristic of the constant contact side bearing is its unique metal to metal design, which can provide more stable operating performance by instantly counteracting the rolling vibration of the bogie. This design can weaken the friction and energy of the bogie before its vibration affects vehicle stability and causes component wear.

The side bearing height is 5.95 “=1/8″ [151mm].

The vertical stiffness of the bearing conforms to: when the working height of the TCC-IV 45 LT side bearing is 5.06 “=0.06″ [128.5mm±1.5mm], the TCC-IV 45 LT side bearing provides a preload of 4500 Ibs (20017N), When the working height of the side bearing is 5.06 [128.5mm], the axial displacement of the side bearing is 0.009 “-0.051″ [0.2mm -1.3mm].When the working height of the TCC-IV 60 LT side bearing is 5.06 “=0.06″ [128.5mm±1.5mm], the TCC-IV 60 LT side bearing provides a preload of 5294 Ibs (23533N),When the working height of the side bearing is 5.06 [128.5mm], the axial displacement of the side bearing is 0.009 “-0.051″ [0.2mm -1.3mm].

TCC-IV-45 LT and TCC-IV 60 LT side bearing process meet the relevant requirements of AAR M-948 as specified.

Product Information

Our advantages

Introducing our TCC-IV long travel constant contact side bearings, designed for the rigorous demands of high speed, high mileage applications. The robust and heat-resistant design of these side bearings maximizes their service life and ensures peak performance even under the most demanding conditions. One of the key features of our constant contact side bearings is their unique metal-to-metal design. This design allows them to immediately counteract bogie rolling vibrations, thereby enhancing stability during operation. By mitigating friction and energy before they impact vehicle stability and cause component wear, our side bearings provide a more reliable and efficient solution. Our TCC-IV long travel bearings have a side bearing height of 5.95 inches (151 mm) and meet vertical stiffness requirements. When the TCC-IV 45 LT side bearing has a working height of 5.06 inches (128.5mm), it provides a preload of 4500 lbs (20017N) and an axial displacement range of 0.009 to 0.051 inches (0.2mm -1.3mm). Likewise, the TCC-IV 60 LT side bearing provides a preload of 5294 lbs (23533N) and axial displacement within the same range at a working height of 5.06 inches (128.5 mm). Rest assured that our TCC-IV-45 LT and TCC-IV 60 LT side bearings meet the relevant standards of AAR M-948.
