Reference OE/OEM Number:
Interchange Part Number:
- High strength overlay plate with reduced thickness for improved fatigue properties
- Hardened steel backs on all rod bearings to improve the support of the bearing lining and assist with bearing retention in the housing
- Increased crush for improved bearing retention
- Elimination of flash plating on the back of the bearings to improve heat transfer through the bearings and to maximize the grip between the bearings and its housing.
- Increased eccentricity to compensate for bore distortion at high rpm and to assist in the formation of hydrodynamic oil films
- 3/4 grooved Main Bearings to optimize bearing load carrying surface area and oil flow to the conrod bearings
- Tight consistent wall tolerances to help you maintain consistent clearances
- Enlarged ID chamfers on bearing edges where required to accommodate large fillet radius on performance crankshafts
Sizes:
Most bearings models are manufactured in different dimensions:
- HX/STDX -0.025 mm / STD +0.000 mm / +0.025 mm / +0,25 mm / +0.50 mm
- All dimensions above are for STD size bearings
- (For HX bearing size, the "Max. Wall at Crown" reduce 0.001" for extra oil clearance)
Please check carefully which size you are bidding for! Check part number
If you need another size than listed here, please ask us if they are in stock. Then please state what size bearings you need in the notes.
What is HX/STDX bearing?
Suitable for high to extreme power applications where additional clearance is beneficial in providing:
- Additional oil flow through the bearings to both improve delivery to high load zones and enhancing cooling.
- Allowing for increased housing distortion under very high inertial and firing loads.
- Providing space for specialised anti-friction coatings that beneficially moderated bearing to shaft surface interactions.
