UMZ Metric Tapered Roller Bearings

1. Product Overview
UMZ metric tapered roller bearings are designed and manufactured in accordance with ISO standards. With tapered raceways on both the inner and outer rings, these bearings can carry combined loads (radial and single-direction axial loads). Their separable design allows the cone assembly (inner ring, rollers, and cage) and the cup (outer ring) to be mounted independently, ensuring convenient installation and adjustment.

2. Design Features

Adjustable contact angle – preload and clearance can be adjusted to optimize stiffness and bearing life.
High load capacity – long rollers with large contact areas provide excellent performance under heavy loads.
Low friction operation – precision-ground raceways and roller ends reduce heat and wear.
Global interchangeability – fully compliant with international metric standards, ensuring compatibility with major global brands.

3. Common Metric Series
UMZ offers a wide range of metric tapered roller bearings to meet diverse applications:

30000 Series – lightweight design, ideal for automotive transmissions and small machinery.
31000 Series – higher load capacity, widely used in trucks and tractors.
32000 Series – versatile series, suitable for automotive wheel hubs and construction equipment.
33000 Series – extra capacity for heavy-duty machinery and industrial gearboxes.
33100 / 33200 Series – larger contact angle, optimized for higher axial loads.
