The NTN SES series is an insert ball bearing with an extended inner ring, made to sit in split plummer block housings and bearing units. Set screws hold it on the shaft, and the design absorbs small alignment errors. It fits power transmission equipment, conveying systems and general machinery where space is tight and mounting needs to be straightforward.
Reading the SES code is simple once you know the pattern. The three letters mark the series: extended inner ring, set screw locking. The digits that follow tie the code to a bore size and bearing size, so SES201 is a 12 mm bore, SES202 a 15 mm bore, SES203 a 17 mm bore, SES204 a 20 mm bore, SES205 a 25 mm bore and SES206 a 30 mm bore. A hyphenated suffix signals an inch bore instead, as in SES204-12 or SES205-16 (3/4" or 1"). That is how the same series covers both metric and imperial shafts.
You will see this series across many industrial settings: belt conveyors, bucket elevators, mixers, fans, pumps, agricultural machinery and process equipment. Food processing, cement, mining and aggregate operations also rely on it. It carries radial loads and moderate axial loads, and because mounting and replacement are uncomplicated, it suits equipment where maintenance windows are short.
Selecting the right unit starts with the shaft diameter, then the housing type, then the operating conditions. Match the bore to the shaft, metric or imperial. Check the sealing arrangement, since these bearings typically use lip seals to hold lubricant in and keep contaminants out. Lubrication matters: many models arrive pre-lubricated and can be relubricated through a passage in the outer ring. When mounting, align the assembly and tighten the set screws to the recommended torque so the inner ring does not slip on the shaft.
On interchangeability, insert bearings from other makers that share the same dimensional nomenclature can serve as replacements. Lines such as SKF YAR, FAG 162, NSK RLS or Timken GY are common cross-references, as long as bore, outer dimensions and locking style line up. Materials and tolerances differ between manufacturers, so confirm compatibility before you swap. If anything is unclear, send us the original part number and we will help you sort it out.
