The Bearing UCP 215 is a mounted pillow block ball bearing unit designed for heavy-duty applications, featuring a large bore capacity and robust design, intended for the mounting of a 75mm shaft, which is both rotated and subjected to heavy radial loads. It combines the UC 215 insert ball bearing with the robust P 215 cast iron two-bolt housing in one pre-assembled unit, without the need for any on-site machining, fitting, or pre-assembling.
The unit has a dynamic load rating of 66.3 kN and a static load rating of 49.0 kN, making it one of the units in the range with the highest capacity. It is designed to accommodate loads more than five times heavier than the UCP 204, over 50% heavier than the UCP 211, thus placing it firmly in the large bore, heavy-duty category of the insert ball bearing unit range. At 8.16kg, it is also the heaviest of the standard range of UCP units. It requires careful planning, robust support, and handling during the installation process.
If we consider all the global manufacturers of such products, i.e., NTN, NSK, FYH, Timken, FAG, and many more, we find that when it comes to UCP 215, the top choice for engineers and procurement managers is the SKF product, considering their guaranteed load ratings, top-grade steel specifications, their superior design of a nylon patch set screw locking mechanism, and their extensive published documentation. This product is manufactured according to JIS B 1558 standards and is fully interchangeable with all other top-grade brand products.
The UCP 215 weighs 8.16 kg, so it needs two people to handle it or a machine to lift it when you are installing it. You have to follow these steps carefully because if you make a mistake with something this big, it can be very expensive and even dangerous.
UCP 215 comes pre-greased with SKF LGMT 2-grade lithium-calcium mineral greases. The nipple is in the middle and needs a straight-head grease coupler. Amount of grease to be added: around 18-22 grams per relubrication. Only inject at low pressure — high-pressure injection in this bore size may cause the seals to be damaged.

The UCP 215 is a large-bore, heavy-duty pillow block (plummer block) ball bearing unit consisting of a UC 215 insert ball bearing inside a P 215 cast iron two-bolt housing. It supports a 75mm rotating shaft with a 66.3 kN dynamic load rating and is used in heavy industrial conveyors, large fan drives, mining equipment, pump installations, and demanding agricultural machinery.
The standard UCP 215 has a metric bore of 75mm. Imperial bore variants using the same P 215 housing include UCP 215-44 (2-3/4 inch / 69.85mm), UCP 215-45 (2-13/16 inch / 71.44mm), UCP 215-46 (2-7/8 inch / 73.03mm), and UCP 215-47 (2-15/16 inch / 74.61mm). All variants share the identical housing footprint, bolt hole pattern, and mounting dimensions.
The SKF UCP 215 has a dynamic load rating (C) of 66.3 kN and a static load rating (C₀) of 49.0 kN. The limiting speed under standard grease lubrication is 2,100 r/min. These are among the highest load ratings in the standard UCP 200-series, making the UCP 215 suitable for large-shaft, heavy-duty industrial shaft support applications.
The UCP 211 has a 55mm bore with a 43.6 kN dynamic load rating and weighs 3.60 kg, with a 171mm bolt hole spacing. The UCP 215 increases to a 75mm bore and a 66.3 kN dynamic load rating — approximately 52% stronger — weighing 8.16 kg with a 217mm bolt spacing. The UCP 215 also has a lower limiting speed (2,100 vs 3,200 r/min), reflecting the larger size. Both use a pressed steel cage in the insert bearing.
The SKF UCP 215 weighs 8.16 kg — the heaviest of the commonly stocked standard UCP 200-series sizes. Shipping weight, including packaging,g is typically 9.5–10.5 kg per unit. Two-person handling or mechanical lifting assistance is strongly recommended during installation due to the combination of weight and the precise positioning required during shaft insertion and set screw tightening.
The recommended set screw tightening torque for the UCP 215 is 45–55 Nm. Tighten both set screws alternately in two stages — first to 50% of the final torque, then both to full torque — using a calibrated torque wrench. After the first 8 hours of operation under load, re-check and re-torque both set screws, as initial bedding of the nylon patch may cause slight relaxation.
