CAT 356-5975 RETAINER

CAT 356-5975 (3565975) is a Caterpillar genuine bearing retainer, primarily used for axial positioning of the outer ring of bearings in gearboxes, final drives, or hydraulic pumps to prevent component movement. It is suitable for low-to-medium speed and medium-load conditions. The following is precise original part information for Cat®…:

Core Parameters and Compatibility Information

Item Details
Part Model: CAT 356-5975 Genuine bearing retainer, weighing approximately 0.22 kg (0.485 lb), suitable for low-to-medium speed and medium-load shaft/bearing positioning scenarios, used to fix the outer ring of the bearing and eliminate axial clearance. Suitable for shaft end structures with a pin diameter of approximately 42 mm.

Core Material: Medium carbon alloy steel sheet, stamped and formed, with galvanized passivation treatment for rust and corrosion resistance. Suitable for outdoor humid and dusty conditions, preventing loosening or jamming caused by rust. Structural strength and durability meet general operating requirements.

Key Dimensions: Inner diameter approximately 47.00 mm 1.850 in diameter, outer diameter approx. 60.00 mm (2.362 in), total thickness approx. 9.00 mm (0.354 in), with locating step, mounting hole tolerance H7, interference fit with bearing outer diameter, interference 0.01-0.03 mm

Structural Features: Annular locating step design, burr-free edges, precise fit between inner hole and bearing outer diameter, axial positioning to prevent movement, ensuring bearing and shaft coaxiality, suitable for low-to-medium speed conditions, compact structure, and easy installation.

Compatible Models: Compatible with CAT C9.3/C13 engines, 966K/972M loaders, 140M/160M graders’ gearbox output shaft, final drive hub shaft, or hydraulic pump drive shaft, used for locating radial bearings/needle roller bearings, suitable for low-to-medium speed and medium load conditions.

Accessories: Compatible with CAT 5P-3510 bearing puller, 4C-9520 mounting punch, and CAT… For use with 186-2915 needle roller bearings and 360-2326 YM sleeve bearings, installation requires a tight fit with the bearing end face for precise positioning.

Core Functions and Installation Points

Positioning and Anti-migration: Axially positions the bearing to prevent axial movement during operation, ensuring coaxiality between the bearing and shaft, reducing localized wear and jamming, and suitable for low-to-medium speed, medium-load oscillating/rotating conditions.

Installation Specifications: Clean the mounting holes, retainer, and bearing surface. Inspect the retainer for deformation, cracks, rust, or other damage.

First, cold press the bearing into the mounting hole. Then, install the 356-5975 retainer into the positioning groove, ensuring a complete fit with the bearing end face without gaps.

Tighten to the torque specified in the machine manual (usually 9-13 N·m). After installation, check that the bearing rotates freely without jamming, abnormal noise, or axial movement/backlash.

Maintenance Recommendations: Check the fastener’s tightness, surface rust, and deformation every 500-700 working hours. Replace with genuine parts immediately if loose, deformed, or severely rusted.

Use only genuine CAT 356-5975 parts to avoid mismatched dimensions/materials that could lead to positioning failure, accelerated wear of the shaft and mounting holes, or component failure.
