Product description of TIMKEN Bearing LM245848 - LM245810

TIMKEN Bearing LM245848 - LM245810, Tapered Roller Bearings TDI (Tapered Double Inner) Imperial. Timken® tapered roller bearing assemblies are precisely designed to manage both radial and axial loads, even in the most unforgiving conditions.Double- or two-row Timken® tapered roller bearings feature double cups and two single cones. They are available in a variety of configurations for general industrial and automotive applications.

This is the most basic and most widely used type of tapered roller bearing. It consists of two main separable parts: the inner race assembly and the outer race. It is typically mounted in opposing pairs on a shaft.

Size Range
ID 7.937 to 1562.100 mm (0.31225 to 61.5000 in.)
OD 31.991 to 1806.575 mm (1.2595 to 71.1250 in.)

TIMKEN Bearing LM245848 - LM245810, Tapered Roller Bearings TDI (Tapered Double Inner) Imperial. Design Attributes
Single cone and cup
One-piece pressed steel cage retains rollers on the cone and spaces them evenly
Pin type cages also available

Applications
Vehicle front wheels
Differential and pinion configurations
Conveyor rolls
Machine tool spindles
Trailer wheels
2TS-IM assemblies are comprised of two single-row bearings with an inner and outer ring spacer. In some applications, a shoulder in the bearing housing replaces the outer ring spacer.

Design Attributes:
Steel spacers are used to create Bench End Play (BEP) or Preload (BPL) in the bearing assembly.
Available with or without spacers.
Spacers preset during manufacture.

Applications:
Gear reduction units
Industrial machines
TIMKEN Bearing LM245848 - LM245810, Tapered Roller Bearings TDI (Tapered Double Inner) Imperial. This composite tapered roller bearing has outer and inner races, each of which is built up by a method which includes forming annular inner and outer tapered or frustoconical load-bearing roller path members formed from unheat-treated butt-welded strips of steel, subsequently heat-treating and final grinding these annular members, welding to the large end of the annular inner roller path member a finished side ring, forming an annular roller retainer with circumferentially spaced pocket openings, assembling a complement of tapered rollers in these circumferentially spaced pocket openings of this annular roller retainer, these tapered rollers having spherical surfaces on their larger diameter ends, placing the thus-formed assembly on the thus partially built-up inner race, and welding a smaller side ring to the other end of the annular inner roller path member. These tapered rollers engage a tapered or frustoconical annular inner load-bearing surface on the annular central roller path member of this composite tapered roller bearing inner race, the larger diameter side ring of which has an annular inner surface of spherical curvature mating with the spherically curved surfaces on the larger ends of the tapered rollers. Before welding, the inner roller path member and the side rings are preferably case hardened in the areas actually engaged by the side and end surfaces respectively of the rollers, the remaining area of each ring not so engaged being selectively excluded from the case hardening. This enables the bearing components to be case hardened and precision ground and honed before assembling and welding, preferably by electronic or laser welding to precisely localize the welds.
