ZYSL 30312 bearing tapered roller bearing 30312DJR 130x60x31 mm introduction:

The most basic and widely used taper bearing, the single-row type consists of the cone assembly and the cup. It is usually fitted as one of an opposing pair. During equipment assembly,  taper bearing can be set to the required clearance (endplay) or preload condition to optimize performance.

Single-row taper bearings have positive roller alignment that ensures true rolling motion and generates a “seating force” that pushes the roller against the cone large rib. This seating force prevents the rollers from skewing off apex, thereby keeping them positively aligned and located against the cone large rib. 

Tapered Roller Bearing Material

While other materials may be available, typically, tapered roller bearings are made of high carbon chrome steel due to their expected performance.

Tapered Roller Bearing Heat Treatments

• Through-Hardened: Through-hardened heat treatment gives consistent hardness throughout the component.

• Case-Hardened: Surface hardening combined with a tough, flexible core (Case-Hardened available upon special request only.

Although Through-Hardened bearings have gradually become the preference in heavy-duty commercial trucking applications, we will supply both Through-Hardened and Case-Hardened Tapered Roller Bearings.

Tapered Roller Bearing Advantages

• Dimensional Stability
• Long Life Even In Contaminated Lubricant
• Durable Steel Cage
• Dimensionally Interchangeable With Other Bearing Manufacturers

Typical Applications for Tapered Roller Bearings

Tapered roller bearings are used for heavy-duty, moderate speed applications. Typical applications that will benefit from these durable bearings include:

• Agriculture, Construction and Mining Equipment
• Various Axle Systems
• Conveyance Vehicles
• Gear Box, Engine Motors, Reducers
