2TS-TM (Spacer Assembly with Tandem Mounting)

Where combined radial and thrust load capacity is required, but the thrust component is exceptional and beyond the capacity of a single bearing (within a given maximum OD), two single-row bearings can be mounted in tandem. Appropriate inner and outer ring spacers are supplied.

Size range:

0 to 8 inches. Larger sizes available on request.

Design Attributes

Steel spacers are used to create Bench End Play (BEP) or Preload (BPL) in the bearing assembly.
Spacers preset during maintenance.

Applications

Hydrostatic axial piston pumps and motors

2TS-DM (Spacer Assembly with Direct Mounting)

2TS-DM (Spacer Assembly with Direct Mounting)

2TS-DM assemblies are comprised of two single-row bearings with abutting back facing inner rings and an outer ring spacer with lubricating holes is typical. These are generally used at fixed positions on rotating shaft applications.

Design Attributes

Two single row bearings, with or without a spacer.
When spacers are used, bearing is furnished as a preset, matched assembly.
Spacers available with or without lubricant grooves and holes.

Applications

Gear reduction units
Industrial machines

2TS-IM (Spacer Assembly with Indirect Mounting)

admin — Thu, 20 Feb 2020 20:43:51 +0000

2TS-IM (Spacer Assembly with Indirect Mounting)

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

SR (Two-Row Non-Adjustable)

SR (Two-Row Non-Adjustable)

SR bearings are made to a standard setting range, based on Timken’s Set-Right™ automated setting technique, and are suitable for most industrial applications. They have two spacers and an optional snap-ring for axial location. Because both types are made from popular sizes of single-row bearings, they provide a low-cost choice for many applications.

Size range:

ID 26.987 to 200.000 mm (1.0625 in. to 7.8740 in.)
OD 61.999 to 300.000 mm (2.4409 in. to 11.811 in.)

Design Attributes

Two TS bearings mounted indirectly with cone and cup spacers.
Cup spacer features lubrication slots to allow commercial snap rings to locate bearings axially.
Two J-Line™ Class N bearings with metric envelop and non-metric internal geometry.

Applications

Automotive configurations

TNA (Two-Row Non-Adjustable)

admin — Tue, 18 Feb 2020 23:07:44 +0000

TNA (Two-Row Non-Adjustable)

TNA bearings are similar to the TDO, but the inner race narrow faces are extended to abut and eliminate the need for a separate inner race spacer. Supplied with an in-built clearance to give a standard setting range, these bearings provide a solution for many fixed or floating bearing applications where simplicity of assembly is required.

Size range:

ID 25.400 mm to 1200.150 mm (1.0000 in. to 47.2500 in.)

OD 30.480 mm to 2460.000 mm (1.2000 in. to 96.8504 in.)

Design Attributes

Double cup and two single cones.
Internal bearing clearance controlled by extending the front faces of the cones so they contact each other.
SW variation features chamfers in the bores at the front faces of the two single cones to form a lubrication groove.
SE variation features a backface rib design to accommodate radial lip seals or stamped closure.

Applications

Sheaves
Crane sheaves
Oil-field drilling rig sheaves
Applications where two-row preset bearings are required

TDO (Two-Row Double-Outer Race)

admin — Tue, 18 Feb 2020 23:02:51 +0000

TDO (Two-Row Double-Outer Race)

The configuration of the TDO provides a wide effective bearing spread, making it ideal for applications in which overturning moments are a significant load component. TDO bearings can be used in fixed positions or allowed to float in the housing bore.

Size range:

ID 25.400 mm to 1200.150 mm (1.0000 in. to 47.2500 in.)
OD 30.480 mm to 2460.000 mm (1.2000 in. to 96.8504 in.)

Design Attributes

Double cup and two single cones, with or without a spacer.
When spacers are used, bearing is furnished as a preset, matched assembly.
Cup features groove and lubrication holes in the OD.
Spacers available with or without lubricant grooves and holes.

Applications

Heavy-duty gear drives
Various industrial configurations

TDI (Two-Row Double Inner Race)

admin — Tue, 18 Feb 2020 22:57:57 +0000

TDI (Two-Row Double Inner Race)

TDI bearings have a one-piece double inner race and two single outer races and are typically supplied complete with an outer race spacer as a pre-set assembly. The bearing can be used at fixed positions on rotation shaft applications. For rotating housing application it can be used to float on the stationary shaft.

TDI bearings are sometimes used on rotating shaft applications where a loose fit is required for ease of removal.

Size range:

ID 25.400 mm to 1200.150 mm (1.000 in. to 47.2500 in.)
OD 30.480 mm to 2460.000 mm (1.2000 in. to 96.8504 in.)

Design Attributes

Double cone and two single cups, with or without a cup spacer.
Furnished as a matched assembly.
Cups ground to fit.

Applications

Gear reduction units
Cranes
Calendar rolls
Industrial machinery
