Overview
The INA KR19-SK-PP is a precision stud-mount crowned cam follower bearing from Schaeffler’s proven KR series. Engineered for demanding industrial motion-control applications, this 19 mm roller features a crowned outer surface for superior load distribution, needle roller construction, and sealed enclosure for reliable operation across manufacturing equipment, automation machinery, and material handling systems.
Key Features
- Crowned roller design — distributes radial loads evenly and tolerates minor misalignment
- Sealed construction — axial guidance and dual-side plain washers protect against contamination
- Needle roller bearing — cage-guided for smooth, compact operation
- High load capacity — 3500 N dynamic, 4000 N static radial load rating
- Wide speed range — rated to 11,000 rpm maximum in standard operation
- Metric thread — M8 × 1.25 stud with 10 mm thread length for secure mounting
Technical Specifications
Operating temperature range of −30 to 100 °C ensures performance across climates and thermal conditions. The stud features hexagonal head geometry for tool-wrench mounting and is supplied uncoated (bare steel) for flexible finish integration in your assembly.
Typical Applications
- Cam-driven transfer lines and indexing tables
- Automated packaging and filling machinery
- Industrial conveyor systems with profiled track cams
- Motion-control equipment requiring axial-load tolerance
