CAT 9T-0064 is a Caterpillar genuine single-row deep groove ball bearing, suitable for high-speed rotating parts such as engines and transmission systems. The following are precise original factory specifications and application information, excluding replacement parts.
Core Technical Parameters
Item Details
Part Model: CAT 9T-0064 (Single Row Deep Groove Ball Bearing with Stamped Steel Cage)
Product Type: Deep Groove Ball Bearing for High-Speed Rotary Supports, suitable for applications with predominantly radial loads and minor bidirectional axial loads.
Material: Inner/Outer Ring: Chromium Bearing Steel (AISI 52100), Rollers: Chromium Bearing Steel, Cage: 08F Stamped Steel, Seal: Nitrile Rubber (NBR)
Key Dimensions: Inner Diameter 30 mm (1.181 in), Outer Diameter 62 mm (2.441 in), Width 16 mm (0.630 in), Chamfer 1 mm, Radial Clearance C3 (0.010–0.025 mm)
Rated Parameters: Rated Dynamic Load 13.2 kN, Rated Static Load 6.55 kN, Limiting Speed (Grease Lubrication) 6000 r/min, (Oil Lubrication) 7500 r/min
Suitable Operating Conditions: Operating Temperature -30℃ ~ +120℃, suitable speed ≤ 6000 r/min, suitable vibration acceleration ≤ 10 g
Single weight: Approx. 0.19 kg (0.42 lbs)
Lubrication: Lithium-based grease (NLGI 2), replenishment interval 1000 hours, do not mix different types of grease
Structure and Core Characteristics: Standard deep groove ball bearing structure: Composed of outer ring, inner ring, steel balls, and stamped cage, with double-sided contact seals for dust and leak prevention, suitable for high-speed, low-noise operation.
High Hardness and Wear Resistance: Bearing steel is quenched and tempered to a hardness of HRC 60–64. Roller surfaces are ultra-precision ground to reduce friction and wear, extending service life.
Low Friction and Low Vibration: Deep groove ball design for high-speed rotation, lightweight stamped steel cage for smooth operation, and noise ≤ 65 dB (@ 3000 r/min). Universal Compatibility: Compatible with various Caterpillar engine accessories, hydraulic pumps, and high-speed rotating shaft ends of transmission systems, offering strong interchangeability.
Compatible Models and Application Scenarios
Compatible Equipment: Generator, water pump, and hydraulic pump shaft ends for CAT 305/306 mini excavators, 3024C/3027C engines, and 906/907 loaders, as well as gearbox input/output shaft supports.
Core Application: Installed between the high-speed rotating shaft and the housing bore, it provides radial support, absorbs a small amount of axial movement, ensures smooth operation of rotating components, and reduces power loss and component wear.
