The CAT 6I-1002 is a Caterpillar genuine single-row deep groove ball bearing, suitable for high-speed rotating shafts in engines, hydraulic pumps, or gearboxes. It is used in applications requiring primarily radial loads, low friction, and high speeds. The following are precise original factory specifications and application information, excluding replacement parts.
Core Technical Parameters
Item Details
Part Model: CAT 6I-1002 (Single Row Deep Groove Ball Bearing, Open Design)
Product Type: General-purpose deep groove ball bearing for engineering machinery, suitable for engine accessories, hydraulic pump drive shafts or gearbox countershafts, bearing radial loads and capable of withstanding small amounts of bidirectional axial loads.
Material: Rings/Rolling Elements: AISI 52100 bearing steel, hardness HRC 60–64; Cage: Stamped steel plate, surface passivated.
Key Dimensions: Inner diameter 35 mm (1.378 in), outer diameter 80 mm (3.150 in), width 21 mm (0.827 in), chamfer 1.5 mm, fit tolerances: inner ring k5, outer ring G6.
Rated Load: Basic dynamic load rating 35.2 kN, basic static load rating 19.5 kN, ultimate radial load 70.4 kN.
Speed Parameters: Grease lubrication limiting speed 6300 rpm, oil lubrication limiting speed 8000 rpm. RPM, compatible with mineral oil-based grease/gear oil
Sealing and Lubrication: Open type without seal rings; lithium-based grease (NLGI 2 grade) must be applied after installation. Operating temperature: -30℃ ~ +120℃
Single Weight: Approx. 0.42 kg (0.93 lbs)
Other Characteristics: Radial clearance C3 group (0.015–0.035 mm), adaptable to clearance compensation under temperature variations and vibration conditions.
Structure and Core Characteristics:
High-efficiency transmission: Deep groove ball bearing structure adapts to high-speed rotation; low coefficient of friction (μ≤0.0015), reducing power loss, suitable for high-speed drive requirements of engine accessories and hydraulic pumps.
Load adaptability: Can withstand radially dominant composite loads; small axial loads do not require additional thrust bearings, simplifying shaft design.
High reliability: Bearing steel material and precision machining; raceway surface roughness Ra ≤ 0.08 μm, reducing wear and noise, and extending service life.
Compatible Models and Application Scenarios
Compatible Equipment: 306E2/307E2 excavators, 906H loaders, C4.4/C6.6 engines, hydraulic main pump drive end, gearbox sub-shaft support.
Core Application: Mounted on the engine fan shaft, hydraulic pump input shaft, or gearbox intermediate shaft, providing radial positioning and rotational support, suitable for high-speed, low-impact continuous operation.
