CAT 149-8652 BALL

CAT 149-8652 is a Caterpillar genuine spherical bearing (self-aligning, single-slotted outer ring), suitable for articulated or oscillating mechanisms in graders, loaders, and other equipment. It automatically compensates for installation misalignment and angular deflection, and can withstand heavy radial loads and light axial loads. The following are the original manufacturer’s precise specifications and application information, excluding replacement parts Cat®…

Core Technical Parameters

Item Details
Part Model: CAT 149-8652 (Spherical Bearing, Self-aligning, Single-slot Outer Ring, with Lubrication Groove)

Material: Inner Ring / Outer Ring: 52100 Chromium Bearing Steel, Hardened to HRC 60-64; Rolling Elements: Hardened Steel Balls / Rollers; Cage: Stamped Steel Plate; Single-slot design for outer ring, adaptable to angular deflection compensation

Key Dimensions: Inner Diameter 38.1 mm (1.500 in), Outer Diameter 63.5 mm (2.500 in), Width 25.4 mm (1.000 in), Spherical Radius 25 mm, Adaptive Hinge Pin Diameter 38 mm

Single Weight: Approx. 0.32 kg (0.705 lbs)

Tolerances: Inner Diameter Tolerance P6 (+0.018/0 mm), Outer Diameter Tolerance P6 (0/-0.025 mm), Width Tolerance ±0.15 mm, spherical roundness tolerance ≤ 0.012 mm

Core Characteristics: Dynamic load capacity 42 kN, static load capacity 68 kN, limiting speed 2800 rpm (grease lubrication), operating temperature -40℃ to +120℃, maximum allowable angle deflection ±2.5°, suitable for the angle compensation requirements of swing mechanisms.

Structure and Core Functions:

Angle Compensation: The single-slit outer ring and spherical contact design automatically compensates for installation coaxiality deviations and angular deflections during operation, eliminating deflection stress on the shaft and bearing, and improving the stability of the mechanism.

Heavy Load Bearing: Suitable for radial heavy load conditions, capable of withstanding impact loads transmitted by swing mechanisms, and suitable for the support requirements of frequently swinging components such as grader blades and loader booms.

Lubrication Adaptability: With lubrication groove design, grease can be periodically added through grease nipples to ensure sufficient internal lubrication of the bearing, extend service life, and suit the dusty and high-vibration operating environment of construction machinery.

Compatible Models and Application Scenarios

Compatible Equipment: CAT 12H, 12G, 140H graders, 983B tracked loaders, 414E backhoe loaders, PR-1000C cold milling machines, etc.

Core Uses: Installed in articulation pins, swing shafts, etc., for grader blade swing mechanisms, loader boom hinge points, etc., providing angle compensation and heavy-duty support, adapting to frequent swinging and impact load conditions, ensuring operational accuracy and mechanism durability.
