CAT 5P-0356 BEARING-NEED

CAT 5P-0356 is a Caterpillar genuine stamped outer ring full complement needle roller bearing, suitable for radially heavy-duty components in tight spaces such as gearboxes and drive shafts. The following is precise original part information:

Core Technical Parameters
Item Details
Part Model: CAT 5P-0356 (5P0356) stamped outer ring full complement needle roller bearing, weighing approximately 0.08 kg (0.176 lb), without an inner ring, directly serving as the raceway for the journal, requiring matching with shaft shoulders and thrust washers for positioning.

Core Material: High carbon chromium bearing steel (52100/SUJ2), outer ring stamped and hardened, needle rollers integrally hardened, hardness HRC 60-64, needle roller surface ultra-fine ground, raceway roughness Ra≤0.2 μm

Key Dimensions: Inner diameter 30 mm (1.181 in), outer diameter 42 mm (1.654 in), width 22 mm mm (0.866 in), needle roller diameter 3 mm, quantity 32, outer ring and housing fit tolerance J7, journal surface hardness ≥HRC 58

Structural Features: Stamped outer ring full complement needle roller design, strong radial load capacity, no inner ring structure saves installation space, suitable for low-speed heavy load, radial space limited gear shaft or drive shaft support

Compatible Models: CAT 320C/320D excavator (slewing gearbox planetary gear shaft), 950G/962G loader (gearbox intermediate shaft), 140H grader (transfer case input shaft), etc. transmission systems

Accessories: Thrust washer 6V-7854, shaft elastic retaining ring 586-7419, sealing ring 456-1559

Core Functions and Structural Features: Compact heavy load adaptation: no inner ring + The stamped outer ring design features a small radial section height, allowing for compact installation in transmission systems. Full complement needle rollers provide high radial load capacity, suitable for low-speed, heavy-load gear shaft applications.

High-precision positioning: The needle rollers make line contact with the journal, ensuring uniform load distribution. Radial clearance is controlled within 0.01-0.02 mm, guaranteeing radial positioning accuracy of the shaft system and reducing transmission vibration and noise.

Strong wear resistance and fatigue resistance: High-carbon chromium bearing steel is hardened, and the mating surfaces of the needle rollers and journal are ultra-precision ground, enhancing fatigue and wear resistance, making it suitable for high-frequency impact conditions in engineering machinery.
