(46) HMVC-10 through HMVC-64 have American National Threads Class 3.HMVC-68 through HMVC-190 have Acme General Purpose Threads Class 3G. /Asset/timken-hydraulic-nut-with-black-oxide-coating-HMV34.png
Inch DUSTAC™ Shaft Seal
(30)- 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
(10)- 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
(33)- 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. /Asset/Inch-TTU-Take-Up-Unit.jpg
Inch TU Take-Up Unit
(35)- 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.
