Inch DUSTAC™ Shaft Seal

• Suggested for pillow blocks used in extremely contaminated environments, such as taconite mines.
• Provides protection against residual and airborne contaminants that exceeds the triple labyrinth shaft seal.
• Contributes significantly to extending bearing life; reduces costs by helping prevent premature bearing damage.
• Because of its unique design, no special finish is required on the shaft. DUSTAC is a patented device utilizing a V-shaped nitrile ring that rotates with the shaft and applies pressure to the cartridge face to exclude contaminates.

Inch Sine Bar Gage

• Tapered-bore, antifriction bearings are mounted either on adapter sleeves or on tapered shaft seats.
• In cases where tapered bore bearings are mounted directly on the shaft, the shaft must conform to the tapered bore of the bearing to assure proper fit. If a proper fit is not achieved, the results could be:
  • Turning of the bearing inner race on the shaft.
  • Uneven loading of the bearing.
  • Severe inner race hoop stress.
  • Insufficient support (back-up) of the inner race on the shaft.
• All of these conditions could lead to premature bearing damage. Therefore, the manufacture, maintenance and measurement of accurate shaft tapers is important.
• There are two accepted ways of measuring tapered shafts: ring gages and sine bar gages.
• Precision measurement of tapered shafts is difficult with ring gages and may be impossible in the case of large shafts where gages are large, cumbersome and heavy.
• Sine bar gages provide an accurate and easy method of measurement.
• Lightweight and easy to handle and learn, sine bar gages achieve precise gagging of the shaft size and taper.
• A complete set for measurement of 1:12 shaft tapers consists of 3 in, 4 in, 5 1/2 in, 7 in, 10 in and 14 in sine bar gages, sine bar saddle no. T-5491-C, web clamp no. T-5489-A and a wooden box no. T-5224-C. A complete set for 1:30 shaft tapers consists of 4 in, 6 in, 8 in and 12 in sine bar gages.
• Sine bars can be purchased individually, or in any combination of sizes to meet your individual needs.
• All sine bars require a sine bar saddle and web clamp. A wooden box is optional.
• For information on the use of sine bars, prices and delivery, consult your Timken representative.

Inch TTU Take-Up Unit

• The same care taken in the selection of stationary pillow blocks must also be applied to selecting the proper take-up unit.
• Load requirements should be carefully evaluated before specifying a particular take-up assembly.
• Frame assembly and adjusting screw of TTU units are made of steel.
• The bearing housing is cast iron. Steel or ductile iron housings are additional options.
• Units include housing for adapter-mounted bearings only, for either fixed or float position (be sure to specify).
• One stabilizing ring is included for fixed position assemblies.
• Sealing is triple ring labyrinth or end closures.
• For extremely contaminated environments, the DUSTAC seal is suggested.

Note: Speed ratings are found in dimension tables in the spherical roller bearing section.

Inch TU Take-Up Unit

• The same care taken in the selection of stationary pillow blocks must also be applied to selecting the proper take-up unit.
• Load requirements should be carefully evaluated before specifying a particular Timken take-up assembly.
• The pedestal is made of stress-relieved cast iron. End bases are made of ductile iron. The guide rail and screw are steel.
• Units are available with travel lengths from 12 to 36 inches, in 6-inch increments.
• Catalog numbers shown here are for the TU take-up unit only; pillow block assemblies must be ordered separately.
• Both two- and four-bolt pedestals are available and must be specified.
