CAT 5P-9514 Bearing – Ball(Debris Resistant)

The CAT 5P-9514 is a single-row deep groove anti-chip ball bearing designed by Caterpillar specifically for applications such as engine accessories, gearboxes, and hydraulic pumps where chip generation is common. Its core advantages include efficient chip intrusion prevention and stable radial load bearing, making it suitable for medium-to-high speed, light to medium load applications. Complete technical and application information is provided below.

Material and Process
Inner ring/outer ring chromium bearing steel GCr15 (hardened HRC60-64), ball high carbon chromium bearing steel, cage nylon PA66, anti-chip seal is double-lip metal skeleton + nitrile rubber (NBR, temperature resistant – Operating temperature: -30℃ to +120℃; chip protection rating: IP65; dustproof efficiency: ≥98%. Key dimensions: Outer diameter 62mm, inner diameter 30mm, total width 16mm, installation clearance 0.002-0.005mm, weight approx. 0.21kg, compatible with 3 M8 locating bolts (hole spacing 45mm), sealing lip diameter 30mm, limiting speed (oil lubrication) ≤8000rpm. Performance parameters: Basic rated dynamic load 28.5kN, static load 15.2kN, coefficient of friction ≤0.0015, operating temperature -30℃ to +120℃. Installation and maintenance specifications: Preparation before installation: Clean the journal and bearing housing bore, removing metal filings and oil; check the bearing seal for damage and ensure the balls are not stuck; measure the inner diameter of the journal and bearing to ensure a clearance fit (0.002-0.005mm); prepare a torque wrench, installation socket, and lithium-based grease. Installation Steps: Apply grease to the outer ring of the bearing and gently press it into the bearing housing bore by hand (do not strike); use the locating pin for positioning, and tighten the M8 bolts symmetrically to 18-22 N·m; after installation, check that the axial runout is ≤0.05 mm, and add grease to 1/3-1/2 of the bearing cavity volume.

Maintenance and Replacement: Check the bearing temperature (≤75℃) and abnormal noise every 500 hours; replenish grease every 2000 hours; check the bearing clearance every 5000 hours, and replace the bearing if the clearance exceeds 0.1 mm; replacement requires complete disassembly, and it is forbidden to replace the seal ring separately.
