CR1-0881 Tapered Roller Bearings Double Row 42X72X38mm For Wheel Part

Product Name: CR1-0881 Tapered Roller Bearings Double Row 42x72x38mm For Wheel Part

Description:
The CR1-0881 is a precision-engineered double-row tapered roller bearing, specifically designed for automotive wheel hub and wheel part applications. Manufactured from high-quality GCr15 chrome steel, this bearing features a C3 internal clearance and P0 precision rating, ensuring reliable performance under the demanding radial and axial loads, high torque, and rotational stresses encountered in vehicle suspension and wheel systems.

Unlike ball bearings, the tapered roller design of the CR1-0881 provides a larger contact area between the rollers and raceways, enabling it to handle significantly higher load capacities with superior rigidity. This bearing is designed as an open-type configuration (without seals), allowing for integration with external lubrication systems or for applications where specific lubricant requirements must be met. The nylon cage ensures precise roller spacing, minimizes friction, and promotes smooth, efficient operation even under high-speed and heavy-load conditions.

Machined to precise 42x72x38mm dimensions, this robust bearing offers excellent shock load resistance, adjustable axial clearance for optimized preload, and extended service life. Its double-row design provides exceptional load distribution and stability, making it a reliable solution for demanding automotive and industrial applications.

Applications:
This bearing is specifically designed for automobile wheel hub and wheel part replacement, providing dependable performance and durability for passenger vehicles, SUVs, and light commercial vehicles operating under diverse driving conditions.

Additional Technical Insight (Double-Row Tapered Roller Bearing – Open Type)

The CR1-0881 is a double-row tapered roller bearing in an open-type configuration, a premium design for high-load wheel applications where external lubrication is preferred.

• Type & Structure: It consists of two rows of tapered rollers positioned between the inner ring (cone) and outer ring (cup). The tapered geometry allows line contact between the rollers and raceways, with each roller precisely guided by a nylon cage. The open design (without seals) allows direct access for lubrication and heat dissipation.

• Features: The tapered roller design provides exceptionally high radial and axial load capacity, high rigidity, and excellent shock load resistance. The double-row configuration enables the bearing to accommodate combined loads in a compact assembly. As an open-type bearing, it relies on external lubrication systems (grease or oil) for optimal performance and cooling.

• Advantages: Key benefits include superior load-carrying capability compared to ball bearings, adjustable axial clearance for precise preload setting, excellent durability under heavy-duty conditions, and the flexibility to use specific lubricants tailored to operating conditions. The open design allows for efficient heat dissipation and simplified maintenance.

• Target Applications: Primarily used in automotive wheel hubs, wheel parts, and axle systems for passenger vehicles, SUVs, and light trucks. This bearing type is also widely found in gearboxes, industrial gear drives, agricultural machinery, and heavy equipment where high load capacity, reliability, and flexible lubrication options are critical.
