Key Specifications

• Inner Diameter (d): 20 mm
• Outer Diameter (D): 42 mm
• Width (B): 15 mm

Design and Functionality

Tapered roller bearings are designed to manage both thrust and radial loads. They consist of four critical components:

• Cone (Inner Ring)
• Cup (Outer Ring)
• Tapered Rollers (Rolling Elements)
• Cage (Roller Retainer)

The 32004 bearing is engineered to provide high performance and durability, with a geometry that allows for linear contact between the raceways and the rollers. This design helps in managing heavy loads and reducing friction.

Applications

• Automotive Applications: Ideal for use in wheel hubs and transmissions.
• Industrial Machinery: Suitable for use in gearboxes, conveyors, and various heavy machinery.
• Agricultural Equipment: Reliable performance in tractors, combines, and other farm machinery.
• Railway and Transportation: Used in railway axle boxes and other transportation equipment.

Product Benefits

• High Load Capacity: Capable of supporting both radial and axial loads, ensuring optimal performance under heavy loads.
• Durability: Manufactured from high-quality materials for extended service life and reliable performance.
• Versatility: Suitable for a wide range of applications, offering dependable performance across various industries.

Operating Conditions

• Temperature Range: Typically operates effectively within -30°C to 120°C, depending on the type of lubricant used.
• Lubrication: Compatible with various greases and lubricating oils, facilitating smooth operation and long service life.

The 32004 tapered roller bearing is a reliable choice for applications demanding high performance and durability. Its robust construction and precise design ensure long-lasting, efficient operation, making it an excellent option for automotive, industrial, agricultural, and transportation applications.

roller bearing description

The inner and outer ring raceways are segments of cones and the rollers are tapered so that the conical surfaces of the raceways, and the roller axes, if projected, would all meet at a common point on the main axis of the bearing. This geometry makes the motion of the cones remain coaxial, with no sliding motion between the raceways and the outside diameter of the rollers.

This conical geometry creates a linear contact patch which permits greater loads to be carried than with spherical (ball) bearings, which have point contact. The geometry means that the tangential speeds of the surfaces of each of the rollers are the same as their raceways along the whole length of the contact patch and no differential scrubbing occurs.

The rollers are stabilized and restrained by a flange on the inner ring, against which their large end slides, which stops the rollers from popping out due to the "pumpkin seed effect" of their conical shape.

The larger the half angles of these cones the larger the axial force that the bearing can sustain.

Tapered roller bearings are separable into a cone assembly and a cup. The non-separable cone assembly consists of the inner ring, the rollers, and a cage that retains and evenly spaces the rollers. The cup is simply the outer ring. Internal clearance is established during mounting by the axial position of the cone relative to the cup, although preloaded installations without clearance are common.

Metric tapered roller bearings follow the designation system defined by ISO 355.
