Description
CH11686 Bushings are core transmission support components
specifically engineered for Perkins engines, primarily compatible
with the Perkins 400 Series (403D-15, 404D-22), 1000 Series
(103-15, 104-22) engines. It is extensively utilised in compact
construction machinery (e.g., micro excavators, walk-behind
rollers), agricultural equipment (tea pruning machines, small
seeders), portable generator sets (10-30kVA), and industrial
auxiliary equipment (small diesel water pumps, air compressors),
providing precise support and low-friction protection for critical
engine moving components.
Core Applications
Front/Rear Crankshaft Support Protection
The CH11686 bushing is primarily installed at the crankshaft front
oil seal housing or rear flywheel housing interface. Functioning as
a ‘buffer connection’ between the crankshaft and fixed components,
it provides stable support for high-speed crankshaft rotation
(suitable for maximum speeds up to 4000 r/min), limits radial
crankshaft runout (controlled within 0.05mm), and prevents seal
failure or component wear caused by direct friction between the
crankshaft and oil seals/housing. This ensures stable operation of
the crankshaft drive system while reducing engine vibration and
noise generated by crankshaft oscillation. housing, thereby
ensuring stable operation of the crankshaft drive system and
reducing engine vibration and noise caused by crankshaft
oscillation.
Reducing Friction Losses and Extending Component Lifespan
Its inherent low-friction properties create a ‘lubricating medium
layer’ between the crankshaft journals and the fixed housing's
metal surfaces, lowering the sliding friction coefficient below
0.07 (compared to approximately 0.25 for direct metal-to-metal
contact). This substantially reduces friction energy losses;
Simultaneously, it evenly distributes radial pressure during
crankshaft operation, preventing localised stress concentration
that could cause shell bore indentation or wear. This extends the
service life of the crankshaft, housing, and oil seals while
reducing engine maintenance frequency.
Sealing Assistance and Contaminant Barrier
Tailored for the dusty and humid conditions of outdoor machinery,
the CH11686 bushing and oil seal collaborate to form dual
protection. Its precision clearance prevents external dust and
moisture from entering the crankcase, avoiding contamination of
engine oil or wear on crankshaft journals. Simultaneously, it
assists in maintaining internal crankcase oil sealing, preventing
oil leakage along the crankshaft end and ensuring stable oil volume
within the engine lubrication system.
