⚡ At a Glance
- • Fitment Precision: Designed for crankshaft main bearing replacement with clear part referencing
- • Best for: Mechanics and garages replacing or stocking main bearings for compatible engines
- • Not ideal for: Custom or non-standard crankshaft journals that need bespoke machining
Component numbers and position information are provided for straightforward identification. The listing includes standard designation information and an outer diameter value for checking fit.
Reliable crankshaft support – with main bearing design
Main bearings sit at the crankshaft journals to support rotation and maintain alignment. The designation as main bearings indicates their role in carrying radial loads at the crankshaft journals.
Consistent bearing form helps preserve journal alignment and supports engine rebuild work. That clarity reduces uncertainty during replacement tasks.
Standard sizing – with STD designation
The STD marking denotes a standard journal size rather than an undersize or oversize variant. Standard sizing corresponds to common replacement workflows where re-machining is not required.
Standard specification simplifies ordering and reduces the need to measure custom clearances. Workshops can expect a direct-replacement approach when the STD size matches the engine.
