Some
applications demand a high level of precision that cannot be
achieved with standard tapered roller bearings.
For more than 50
years, Timken has offered a wide array of precision-class tapered
roller bearings with reduced
bore and OD tolerances that deliver
superior accuracy and control in critical applications. This greater
rotational
accuracy is required for machine tool applications.
Precision Bearings
Size range:
ID 30 mm to 45 mm (1.811 in. to 1.7717 in.)
OD 58 mm to 80 mm (2.2835 to 3.1496 in.)
Design Attributes
- Tighter manufacturing specifications resulting in greater
rotational accuracy.
- Reduced tolerances on bore and outside diameter, creating
improved performance in high speed, high temperature
applications.
- Straight race and/or roller profile designs (versus crowned
profile designs) for increased accuracy and rigidity.
- Controlled machining and assembly processes to ensure that
components are matched properly and exact specifications are
met.
- High load-carrying capabilities so that bearing fatigue life is
enhanced.
- The ability to be adjusted during installation so that operating
torque, shaft rigidity and operating temperature can be
precisely controlled.
Applications
- Machining
- Printing presses
- Rolling mills
- Optical grinders
- Profile cutters
- Indexing tables
- Machine tool spindles and drive tables
- Rolls for special film and coating process equipment
