The INA PWTR series is a stud-type support roller built to handle high radial loads where the raceway runs directly on the stud. You will see it in cam drives, linear guide systems and lifting mechanisms, and its 2RS sealing suits dusty or humid conditions. MR Industrial Accessories LLC supplies this brand from Miami to customers throughout the United States and Latin America.

Reading the designation helps you specify the right roller. PWTR identifies the stud-type support roller family. The number after it is the stud diameter in millimeters, so PWTR15 has a 15 mm stud, PWTR20 a 20 mm stud and PWTR40 a 40 mm stud. The 2RS suffix means double-lip seals on both sides, which retain lubricant and keep contaminants out. The XL suffix marks the current generation of the product, with optimizations in load capacity and service life.

These rollers appear in packaging machinery, material handling equipment, presses, punching machines and engine cam systems. Food processing plants use them where corrosion resistance and cleanability matter, and metalworking operations rely on them to guide sheet and profiles. Their compact envelope lets them fit into tight spaces while still carrying the required radial load.

Selection comes down to radial load, rotation speed and the working environment. The 2RS seal handles dust, chips and moderate humidity; if the roller faces liquid exposure or pressure washing, plan on extra sealing. During assembly, align the stud precisely with the raceway and avoid side loads, which shorten service life. Most sizes are lubricated for life, which keeps maintenance simple, though severe duty may call for relubrication.

For interchangeability, INA PWTR rollers can be replaced by products from other manufacturers that use the same dimensional nomenclature. Check tolerances and sealing type carefully, because small differences can change performance. MR Industrial Accessories LLC carries the INA brand within its bearing line and can advise on compatibility with other brands.
