Finding the Right Cylindrical Roller Bearing? Focus on These Key Factors

Many buyers struggle with mismatched bearing dimensions causing installation delays, or premature wear from low-quality materials that lead to unexpected downtime. Sourcing from multiple suppliers for different brands only adds complexity to your procurement process.

Engineered for Consistent Performance in Demanding Environments

This cylindrical roller bearing addresses these challenges with interchangeable dimensions compatible with major international standards. Backed by ISO 9001 certified production processes, we offer comprehensive brand coverage—including NTN, Koyo, Timken, and our own BDL brand—all from a single supplier. Whether for hydraulic systems in construction machinery or conveyors in mining operations, this bearing delivers reliable radial load handling.

Optimal Performance in Heavy-Duty Radial Load Applications

Designed for double row radial load support, this bearing excels in applications with moderate misalignment (thanks to its aligning capability) and operates effectively in standard industrial temperature ranges. The 60° contact angle enhances load distribution, making it suitable for equipment subject to steady radial forces such as steel rolling mills and automated production lines.

Critical Engineering Features for Long Service Life

The choice of bearing steel material ensures high surface hardness and wear resistance, critical for withstanding repetitive loading cycles. Available precision ratings from P0 to P2 allow selection based on application accuracy requirements—P5 or P4 grades for machinery requiring tight dimensional tolerances, while P0 suits general industrial use. Clearance options (C0, C3, C4) accommodate thermal expansion needs, with C3/C4 ideal for high-temperature environments to prevent seizure. Steel or brass cages provide durability; brass cages offer superior heat dissipation for continuous operation.

Why Proper Bearing Selection Lowers Total Cost of Ownership

Choosing the right cylindrical roller bearing directly impacts operational costs. A bearing with incorrect clearance can cause overheating and premature failure, leading to unplanned shutdowns and replacement expenses. Our precision-machined 95x170x32 mm dimensions ensure drop-in compatibility, reducing installation time and errors. By selecting the appropriate precision class and cage material upfront, you avoid costly retrofits and extend equipment lifespan—ultimately lowering long-term maintenance支出.
