Manufactured by INA, a renowned brand known for its quality and innovation in bearing technology, this bearing ensures optimal performance, durability, and smooth operation under diverse working conditions.
Key Features of Bearing KR 47-PP-A INA
- Design: The KR 47-PP-A is a drawn cup needle roller bearing with a polyamide cage, which provides excellent guidance and retention of the needle rollers, reducing friction and wear.
- Material: Constructed from high-grade steel to withstand high loads and extend service life.
- Sealing: The “PP” suffix indicates the presence of polyamide cages that contribute to quieter operation and enhanced protection against contamination.
- Compact Size: Its thin-walled design allows integration into assemblies with limited space while maintaining load-carrying capacity.
Technical Specifications
- Inside Diameter (d): 47 mm
- Outside Diameter (D): 55 mm
- Width (B): 6 mm
This compact dimension profile makes the KR 47-PP-A INA ideal for applications where space constraints are critical, such as automotive components, gearboxes, and industrial machinery.
Applications and Benefits
The KR 47-PP-A INA bearing is widely used in applications requiring high radial load capacity with minimal axial space. Thanks to its needle roller construction, it supports heavy radial loads while maintaining a low cross-section. Common applications include:
- Automotive transmissions and engines
- Power tools and household appliances
- Industrial gearboxes and conveyors
- Textile and printing machinery
