Mounted Ball Bearings

PTI offers a wide assortment of housings and ball bearing inserts with more than 700 housing types including European Metric, Asian Metric, and American Standard configurations. Stock product available through 140mm (Metric), 4″ (American Standard). PTI mounted ball bearings are available in all four standard mounting methods – set screw locking, eccentric locking collar, concentric clamp collar, and tapered adapter sleeve.

PTI offers two brands of inserts in set screw and eccentric mount. The PTI Series uses a steel cage and is grease lubricated with a steel flinger and lip seal. The Euro Series is a European brand that uses a molded nylon cage for higher speeds. They are grease lubricated and have a lip seal between two pieces of zinc plated steel.

Corrosion Resistant Mounted Ball Bearings

Corrosion Resistant units from PTI meet the demands of caustic environments and high pressure washdown environments found in the food, beverage, and pharmaceutical industries. Materials include stainless steel, thermoplastic, and nickel-plated.

Take Up Frames

PHUSE Series Take-Up Frames provide for a simple, economical solution in applications requiring the ability to adjust belt tension. They include a Cast Iron housing for the bearing and a Plate Steel cover connected to a threaded rod to allow for tensioning.

TUWS Series Wide Slot Take-Up Frames are fabricated from heavy-duty plate steel. The frames are assembled so that the fit between the frame and mating bearing fit together with less clearance, allowing for smoother operation.

Eich

Eich is the industry leader for high temperature, heavy load bearings. Eich bearings are frequently used in steel mills or applications of extreme temperature such as furnaces or continuous casters.

The spring-wound races with a high tension wrap of high-temp spring steel ensure a tight spring fit onto the shaft as well as into the cylindrical bore of the roll or housing. Eich bearings are designed to operate in the most challenging environments including high temperatures, extreme loads and contaminated conditions.

Eich Roller BearingsEich Roller Bearings

Rod Ends

  • Standard and heavy-duty rated units including designs capable of high-dynamic, high-static axial loads and high speeds.
  • Stainless steel units can be applied in corrosive environments.
  • Right and left, male and female threaded units are all standard stock.
  • Additional rubber seals and neoprene protector caps available.

Power Transmission Components

Shaft Attachments & Couplings

Keyless Bushings offer quick and simple mounting or removal of drive components on straight shafting without a key. The self-centering feature improves balance compared to set screw mounting. When tightened, the interference fit allows high torque, high speed, and a zero backlash.

Weld-on hubs are often used to simplify mounting and popular for large plate sprockets or gears.

The HRC Series elastomeric shaft coupling with TL bushing bore allow the bushing to be easily installed from flange or hub side. Bored-to-size hubs are also available.

TL taper bushings are stocked from 1008 through 5050 sizes covering through 5″ or 125mm shaft sizes.
