Brand: GLOBALMACHEX
SKU: 7J8894
Availability: InStock
Rating: 5 (1 reviews)

7J8894 tapered roller bearing cup (outer race) is a dedicated replacement spare part for axles of heavy Caterpillar wheel loaders 980G, 992C and 994. It is precisely forged and quenched from high-hardness bearing steel with optional P0/P6/P5 precision grades. As the matching outer ring of tapered roller bearing, it cooperates with rollers and inner ring to bear heavy combined radial and single-direction axial loads. Mirror super-finished raceway delivers outstanding wear and impact resistance for harsh heavy-load bumpy mining shoveling conditions. It can directly replace OEM bearing assemblies on site, serving as essential wearable spare parts for axle maintenance and complete machine overhaul of large Caterpillar wheel loaders.

Specifications

Trade Information

7J8894 bearing cup is specially matched for large tonnage Caterpillar wheel loaders 980G, 992C and 994, manufactured fully compliant with Caterpillar OEM drawing dimensions. This separate outer ring can be assembled with matched rollers and inner ring to form a complete tapered roller bearing. It is installed on heavy-load support positions of front & rear axles and final drives of loaders. During full-load ore and earth shoveling work in mines, it continuously bears high-pressure alternating impact loads from rollers. This product features high hardness and minimal stress deformation. The split outer ring structure avoids replacing the whole bearing during maintenance; only replacing the damaged bearing cup can fix faults, greatly reducing maintenance downtime of large loaders and operation losses of mining fleets.

2. Material & Processing Advantages

Integral Forged Bearing Steel Blank: Integrally forged from national standard premium bearing steel with complete quenching and tempering heat treatment. Uniform hardness and stable metallurgical structure of inner raceway and roller contact surface deliver excellent resistance to fatigue, pitting and surface spalling, capable of enduring continuous heavy impact loads in mines.
Mirror Super-Finish Raceway Process: The inner raceway of bearing adopts mirror super-finish grinding with ultra-low surface roughness, which reduces running friction and operating temperature. It avoids high-temperature seizure and abnormal wear during long-term continuous heavy-duty operation.
Precise Outer Diameter Control: Precision turning machining on outer circle of bearing cup with strict tolerance control. It fits tightly into axle housing bore without excessive play, and is not easy to loosen and shift when loaders drive on bumpy roads.
Separate Split Outer Ring Design: The bearing cup is independent from rollers and inner ring. During maintenance, only the worn or damaged outer ring needs to be replaced instead of purchasing a full bearing set, effectively cutting spare parts purchasing costs for construction machinery maintenance.

3. Precision Grade Selection Guide

P0: Standard general precision with outstanding cost performance, suitable for daily shoveling and routine maintenance single cup replacement of loaders in sand plants and small & medium mines
P6: Tighter dimensional tolerance for raceway and outer diameter improves assembly concentricity, reduces running vibration and heat generation, ideal for large mining fleets with 24-hour non-stop heavy-duty haulage
P5: High-precision grade for complete loader overhaul and axle transmission performance upgrade. Higher precision raceway greatly improves high-speed running stability of the full bearing assembly

4. Quality & Installation Instruction

7J8894 bearing cup is strictly manufactured to Caterpillar OEM specifications, no secondary machining such as grinding or reaming required, it can be directly assembled with OEM matched rollers and inner rings. Every finished product passes full inspection on outer diameter tolerance, raceway surface hardness, raceway finish and dimensional accuracy before delivery. Custom P0/P6/P5 precision grades are available for bulk orders.

Installation steps: 1. Thoroughly clean axle housing bore of loader and outer wall of bearing cup to remove silt, grease and impurities; 2. Press the bearing cup in evenly, never strike the raceway directly to avoid bump damage; 3. Fill matched high-temperature special construction machinery lubricating grease after assembly; 4. Assemble rollers and inner ring, debug the axle, and confirm no excessive play or abnormal noise before putting into operation.

5. Application Scenarios

Widely applied to axle and final drive repair of large Caterpillar wheel loaders 980G/992C/994, export wholesale of Caterpillar construction machinery spare parts, and regular equipment maintenance of engineering fleets in large open-pit mines and sand aggregate bases. It solves common failures of original bearing outer rings including raceway wear, surface spalling, pitting, loose abnormal running noise, reduced load capacity and high temperature overheating. The separable bearing cup allows single replacement, greatly saving spare parts purchasing costs for complete overhaul of large loaders.
