30212 TIMKEN 60x110x23.75 Tapered Roller Bearing

30212 TIMKEN 60x110x23.75 Tapered Roller Bearing

30212 TIMKEN is a metric single-row tapered roller bearing measuring 60x110x23.75 mm. Its tapered roller and raceway geometry enables the bearing to accommodate combined radial and axial loads, with axial load acting in one direction.

The bearing has a separable construction. The inner ring with roller and cage assembly and the outer ring can be mounted separately.

TIMKEN identifies the individual components as:

Cone - X30212

Cup - Y30212

The complete X30212/Y30212 arrangement forms the 30212 tapered roller bearing.

30212 TIMKEN - Dimensions

The principal dimensions specified by TIMKEN are:

d - Bore diameter: 60 mm
D - Outside diameter: 110 mm
T - Overall bearing width: 23.75 mm
B - Inner ring width: 22 mm
C - Outer ring width: 19 mm

Complete principal dimensions:

60x110x23.75 mm

For a tapered roller bearing, it is important to distinguish the overall bearing width T = 23.75 mm from the inner ring width B = 22 mm and outer ring width C = 19 mm.

30212 Tapered Roller Bearing Construction

TIMKEN 30212 belongs to the group of metric single-row tapered roller bearings.

Its principal construction consists of:

inner ring

tapered rollers

cage

outer ring

The rollers and raceways have tapered geometry.

This construction enables the bearing to accommodate radial load together with axial load acting in one direction.

The bearing is separable, allowing the cone assembly and cup to be handled and mounted separately.

Radial and Axial Loads

A single-row tapered roller bearing is designed to accommodate combined loads.

TIMKEN 30212 can accommodate radial loads and axial loads acting in one direction.

When axial loads must be supported in both directions, single-row tapered roller bearings can be used in appropriately arranged pairs.

The bearing arrangement and adjustment should be selected according to the requirements of the machine and complete bearing system.

TIMKEN 30212 Load Ratings

For the X30212/Y30212 bearing, TIMKEN specifies:

Dynamic radial load rating C1: 107 kN
Static load rating C0: 117 kN

TIMKEN also specifies the following calculation factors:

e: 0.40
Y: 1.48
K: 1.44

Load ratings are engineering values used for bearing selection and life calculations.

They should not be interpreted as simple maximum machine loads without considering load direction, bearing arrangement, rotational speed, lubrication and required service life.

What Does X30212 Mean?

X30212 is the TIMKEN designation for the cone assembly.

The cone assembly consists of the inner ring together with the tapered rollers and cage.

Because a tapered roller bearing has a separable design, the cone can be handled separately from the outer ring.

What Does Y30212 Mean?

Y30212 is the TIMKEN designation for the cup, or outer ring.

The cup contains the outer raceway on which the tapered rollers operate after the complete bearing has been assembled.

The matching:

X30212 cone + Y30212 cup

forms the complete 30212 bearing arrangement.

How Does a 30212 Tapered Roller Bearing Work?

During operation, the tapered rollers move between the correspondingly tapered raceways of the inner and outer rings.

The geometry of the rolling contact enables the bearing to accommodate combined loading.

This makes tapered roller bearings fundamentally different from standard deep groove ball bearings when significant combined radial and axial loading must be considered.

Correct bearing adjustment is an important part of the complete bearing arrangement.

Separable Bearing Design

One characteristic feature of TIMKEN 30212 is its separable construction.

The:

cone assembly X30212

and

cup Y30212

can be separated.

This allows the inner assembly and outer ring to be mounted separately during machine assembly.

The matching components must form the correct bearing arrangement after installation.

Installation and Adjustment

Correct installation is essential for tapered roller bearing operation.

Important factors include:

correct seating of the rings

clean mounting surfaces

appropriate shaft and housing fits

correct bearing alignment

suitable lubrication

correct adjustment of the bearing arrangement

The required internal setting depends on the complete machine design and bearing arrangement.

Incorrect adjustment can affect friction, operating temperature and bearing service life.

30212 and Other Bearings in the 302 Series

The designation 30212 identifies a specific bearing size within the metric 302 tapered roller bearing series.

A similar designation should not be used as the sole basis for replacement selection.

For TIMKEN 30212, the principal dimensions are:

d = 60 mm

D = 110 mm

T = 23.75 mm

The bearing design, load ratings and requirements of the complete bearing arrangement should also be considered.

Selecting a Replacement for TIMKEN 30212

When selecting a technically corresponding replacement, compare at least:

Bearing type: Single-row tapered roller bearing
Dimensions: 60x110x23.75 mm
Bore diameter d: 60 mm
Outside diameter D: 110 mm
Overall width T: 23.75 mm
Inner ring width B: 22 mm
Outer ring width C: 19 mm
Dynamic load rating: Suitable for the application
Static load rating: Suitable for the application
Bearing accuracy: Appropriate for the bearing arrangement
Lubrication and mounting requirements: Suitable for the machine

Matching the 30212 designation and principal dimensions alone does not establish complete technical interchangeability in every application.
