JCB LIFT Cylinder Spring Bushing 50x56x98mm
Tension bushing (spring bush) designed for mounting the lift cylinder (LIFT) in JCB machinery. This component plays a key role in the boom's kinematic system, reducing friction at the cylinder's pivot point and protecting pins from premature wear. Manufactured from steel subjected to precise thermo-chemical treatment, the bushing is characterized by exceptional resistance to surface pressure and abrasion in harsh, dusty conditions.
Specifications and technical parameters:
- Dimensions: 50 mm (Inside Diameter) x 56 mm (Outside Diameter) x 98 mm (Length).
- Type: Hardened slotted tension bushing.
- Material: High-alloy spring steel, hardened.
- Application: Lift cylinder (LIFT) mounting.
Compatibility with JCB machines:
| Backhoe Loaders |
214/215/217, 3, 3C, 3CS |
| Telescopic Handlers |
504, 520, 526, 528 |
Technical Advice: LIFT cylinder bushings operate under immense dynamic loads. Regular lubrication of the pivot points is essential to maintain a lubricating film within the bushing channels. If any pin play is detected, the bushing must be replaced immediately—delaying repair will lead to the ovalization of the seat in the machine frame or the cylinder eye, resulting in significantly higher costs for hole regeneration. During installation, cooling the bushing (e.g., in dry ice) is recommended to facilitate seating without the risk of damaging the working surface.
