Product Description
Full Product Specifications: Waukesha BEARING FRONT 161309C
1. Basic Product Overview
- Full Part Name: Waukesha 161309C Front Main Bearing
- Product Type: Front crankshaft main bearing (1st main journal) with integrated thrust flange for axial load resistance
- Brand Clarification:
- Waukesha Engine: OEM genuine spare part for Waukesha gas/diesel engines. This component is an engine bearing, not the fluid processing bearings from Waukesha Bearings.
- FRONT: Denotes the bearing fitted at the front end of the crankshaft, with one-piece integrated thrust axial load function.
- Suffix "C" Definition: STD standard size (no undersized/oversized machining allowance, standard stock wall thickness 0.000").
2. Material Standard (OEM Standard Construction)
- Backing Layer: Low carbon steel
- Anti-friction Surface: Multi-layer sprayed tin-lead Babbitt alloy
- Structure: Split two-piece bearing shell with positioning tang on one side, integrally cast thrust flange face
- Temperature Resistance: Continuous operating temperature ≤135°C, instantaneous peak temperature 160°C; compatible with gas/diesel engine oil lubrication.
3. Core Dimension Parameters (Inch + Metric Conversion)
Matching standard crankshaft journal diameter: 2.750 in / 69.85 mm
- Bearing Inner Diameter (assembled standard): 2.750" (69.85 mm)
- Bearing Outer Diameter (block bore fit): 3.0625" (77.7875 mm)
- Single shell axial width: 2.125" (53.975 mm)
- Standard single-side wall thickness: 0.15625" (3.969 mm)
- Overall outer diameter of thrust flange: 3.625" (92.075 mm)
- Single-side thrust face thickness: 0.1875" (4.7625 mm)
- Standard assembly clearance: 0.003–0.006 in (0.076–0.152 mm)
4. Compatible Waukesha Engine Models
- F265 / F265GA / F265LPA gas generator sets
- 190GL / 190GLB / 190DSB / 190DLB industrial gas & diesel engines
- G265 generator sets, oilfield fracturing equipment, biogas power generation complete Waukesha units
- Interchangeable part numbers for the same series: 161309 (base part), 161309C (STD standard size); undersized repair part suffixes: 161309-010, 161309-020
5. Performance & Operating Condition Parameters
- Rated Load Capacity: Max static radial load 12500 lbf (55.6 kN); axial thrust load 4200 lbf (18.7 kN)
- Applicable Rotation Speed: Idle speed 600 rpm ~ rated speed 2200 rpm
- Lubrication Requirement: Industrial SAE 15W-40 / SAE 30 engine oil, oil pressure 0.28–0.42 MPa
- Wear Limit: Replace immediately when shell wall wear loss ≥0.008 in (0.2 mm); maximum allowable thrust face clearance 0.015 in
6. Key Assembly Specifications
- Bearing Free Spread: Unassembled inner diameter is 0.004~0.007 in larger than block bore to ensure full contact and heat dissipation
- Positioning Tang Alignment: Align tang with the oil supply slot in the crankcase, oil groove facing the engine internal lubrication gallery
- Main Cap Bolt Torque: 190–210 ft-lb (258–285 N·m)
