P.T. International Corp. (PTI) was founded in 1994 in Charlotte, NC, and is a leading provider of high-quality Metric and American Standard industrial power transmission components and mounted bearings. PTI is the US partner for select European manufacturers including Winkel heavy linear products and Eich spring bushed steel industrial bearings.
In November 2020, Solve Industrial Motion Group announced the formation and uniting of three strong, established businesses in the industrial bearings and power transmission components industry. The brands include P.T. International (PTI), IPTCI Bearings, and LMS Bearings.
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 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 Bearings
- 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.
- Hydraulic rod ends suited for heavy loads and severe environments.
- Interchangeable with European standards.

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.
Weld-On Taper Bushing Hubs
Belt Drive Products
PTI offers a wide range of cast iron drive components for belted applications.
- Metric XL, L, and H synchronous TL timing pulleys are available for a variety of standard belt widths up to 3″.
- T-Series and AT Series Metric timing pulleys have a a trapezoidal tooth form and are available in sizes: 2.5mm, 5mm, and 10mm. The AT tooth form is a curvilinear pitch, available in two sizes: 5mm and 10mm.
- Metric HTD sprockets are available in 5mm, 8mm, and 14mm tooth pitch in standard widths for HTD belts.
- Metric super-torque TL timing pulleys in 8mm or 14mm pitch sizes.
- Metric V-belt TL sheaves (SPZ, SPA, SPB, SPC) are available up to 1250mm pitch diameter and up to 10 grooves for most sizes.
- Metric variable pitch TL pulleys allow for speed adjustment of the driven shaft and are available in Z, A, and B belt sections.
