Core Parameters and Information

Item Details
Part Model: CAT 009-2782 (0092782) Bushing (Spherical Plain Bearing Inner Ring Bushing)

Part Type: Self-lubricating spherical plain bearing inner bushing, used for wear-resistant isolation between the trunnion and the spherical plain bearing, reducing oscillating friction

Material: Tin bronze CuSn6Zn6Pb3, centrifugal casting, hardness HB80-100, oil content 12-15%

Key Dimensions: Inner diameter 35mm, outer diameter 42mm, thickness 3.5mm, length 55mm, chamfered ends 0.5×45°

Structural Features: Integral thin-walled cylindrical structure, inner surface Brinell hardness HB≥80, outer surface Ra≤0.8μm, compatible with 009-2039 trunnions and 008-3053/3054 Spherical Plain Bearing

Surface Treatment: Overall passivation and rust prevention; self-lubricating coating on the inner bore (PTFE + bronze powder), thickness 0.02-0.03mm

Matching: Interference fit with trunnions (H7/r6, interference 0.02-0.04mm); clearance fit with the outer ring of the spherical plain bearing (D9/h9, clearance 0.05-0.08mm)

Rated Load: Radial rated dynamic load 18kN, static load 40kN, allowable swing angle ±15°, coefficient of friction μ≤0.15

Operating Temperature: -40℃ ～ +120℃

Weight: 0.18 kg

Installation and maintenance points:

Clean the inner bore of the bushing and the surface of the trunnion to remove oil and impurities. The roughness of the bushing inner bore should be Ra≤1.6μm.

Assemble using cold pressing or heating (heat the bushing to 80-100℃). Do not directly strike the end face of the bushing.

Post-installation inspection: The bushing and trunnion should fit tightly without looseness or misalignment. The radial clearance should be 0.04-0.07mm.

Maintenance: Check the bushing wear every 1200 working hours. Replace when the inner diameter wear exceeds 0.1mm or the self-lubricating coating peels off.
