Product Overview

Metric Single Row Tapered Bearings are standardized precision rolling bearings engineered to accommodate combined heavy radial loads and unidirectional axial thrust forces. Designed in accordance with ISO metric dimension standards, these bearings feature inner ring, outer ring, and tapered rollers with contact angles that converge at a common apex point along the bearing centerline to ensure true rolling motion and low dynamic friction. Manufactured from high-purity GCr15 Chrome Steel or case-hardened alloy steel, they are separable components where the inner ring with roller and cage assembly (Cone) can be mounted independently from the outer ring (Cup). Metric single row tapered roller bearings are extensively specified across automotive transmission systems, commercial vehicle axle hubs, industrial reduction gearboxes, agricultural machinery, and construction equipment.

Key Features & Advantages

Standardized Metric Dimensions: Fully compliant with ISO metric dimensional series (302xx, 303xx, 320xx, 322xx, 323xx), ensuring global interchangeability and seamless replacement.

High Combined Load Capacity: Optimized tapered raceway geometry enables simultaneous handling of substantial radial forces and high single-direction axial thrust.

Separable & Simple Mounting: Independent Cup (outer ring) and Cone (inner ring assembly) design simplifies installation, alignment checks, and routine operational maintenance.

Adjustable Internal Clearance & Preload: Axial clearance and operational preload can be adjusted during mounting to optimize system rigidity, rotational accuracy, and service life.

High Rigidity & Reduced Stress Concentration: Crowned rollers and logarithmic raceway profiles distribute contact stresses evenly, preventing edge loading and extending component fatigue life.
