Product Description
This precision-engineered double-row cylindrical roller bearing combines superior performance with exceptional accuracy to ISO Tolerance Class 4 (ABEC.7). Featuring dimensions of 85mm (bore) x 118mm (OD) x 34mm (width), this bearing is designed for applications demanding high radial load capacity and precise operation.
Key specifications include:
- M2 design with two-piece machined brass cage for optimal roller guidance
- Tapered bore with 1:12 taper ratio (K designation)
- C1NA non-interchangeable radial internal clearance, specifically for cylindrical roller bearings
- P4 precision rating - exceeding P5 accuracy standards
- C1 internal play configuration (tighter than C2 standard)
The bearing construction features:
- Separable outer ring design for easier maintenance and installation
- Double row of cylindrical rollers with precision cage guidance
- Robust flange-guided rolling elements
- Superior radial stiffness and load handling capacity
Ideal applications include:
- Machine tool main spindles
- High-precision industrial equipment
- Applications requiring exceptional rotational accuracy
- Heavy-duty machinery with high radial loads
The specially designed cage system prevents roller-to-roller contact, resulting in reduced friction, lower heat generation, and capability for higher operational speeds compared to full-complement designs. This makes it particularly suitable for high-speed precision applications where reliability and accuracy are paramount.
