KG140BH6R Bearing Product Overview & Core Advantages
The KG140BH6R is a thin-section angular contact ball bearing engineered for applications demanding high precision and space optimization. This single-row bearing features a 30° contact angle, enabling it to support significant combined loads—handling both radial and axial forces simultaneously. Manufactured to ABEC 7F tolerance standards, it delivers exceptional running accuracy and rotational stability. Its large 14-inch bore and compact 1-inch cross-section make it ideal for high-rigidity support in weight-sensitive and compact designs.

KG140BH6R Bearing Structural Features & Performance Benefits
Optimized Thin-Section Design: With only 1" width and large 14" bore diameter, this bearing provides maximum load capacity in minimal space, making it perfect for compact machinery and weight-critical applications.
High Precision Performance: Manufactured to ABEC 7F tolerance class with extremely tight dimensional tolerances (±0.0014") and minimal radial internal clearance (0.0000-0.0005"), ensuring smooth operation and precise positioning.
Superior Load Capacity: The 30° contact angle and optimized raceway geometry deliver exceptional combined load handling with radial dynamic rating of 11,338 lbf and axial static rating of 28,360 lbf.
Advanced Material Construction: Features chrome steel rings and balls with phenolic cage for reduced weight, corrosion resistance, and smooth operation across the temperature range of -30°C to 110°C.
