How the NUP208-ECP model number is decoded

For a 40 mm shaft, SKF lists NUP208-ECP as single-row caged cylindrical roller: 80 mm OD, 18 mm wide, Pu 6.7 kN, the catalogue lists 9,500 r/min thermal reference speed and 11,000 r/min mechanical limiting speed. The NUP configuration means two integral flanges on the outer ring plus one integral flange and one loose flange ring on the inner ring; functionally the bearing is a locating bearing that positions the shaft axially in both directions while keeping the cylindrical-roller radial capacity. Reading the order-string suffix ECP: the E-design execution with a glass-fibre reinforced polyamide (PA66) cage, limited to 120 °C continuous. With C 62 kN and C0 53 kN, size the bearing on the 40×80 mm ISO 15 envelope and check the 6.7 kN Pu against the equivalent-load floor; the catalogue lists 9,500 r/min thermal reference speed and 11,000 r/min mechanical limiting speed. Fit practice for NUP208-ECP: the loose inner-ring flange must be fitted on the correct side and retained by the shaft abutment; never omit it during reassembly or the bearing loses its two-direction locating function. Single-row cylindrical rollers tolerate only about 3–4 minutes of arc misalignment, so verify shaft and housing alignment.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Do not use a NUP bearing where a floating non-locating bearing is required — the loose inner flange makes it a locating bearing
• The dimension series 2 (light-section ISO 15 envelope) envelope is shared with the N/NU/NJ/NUP executions of 208, but flange configuration and axial-locating behaviour differ — quote the full SKF NUP 208 ECP and do not substitute rib styles without checking the shaft locating scheme.
• Press-fit force goes through ring faces only; driving a ring home through the rollers brinells the 80 mm raceway.
• Press-fit force goes through ring faces only; driving a ring home through the rollers brinells the 80 mm raceway.
• The 62/53 kN ratings are SKF catalogue 17000 (2018) values for the ECP execution; re-verify against the current catalogue for critical drives and keep the catalogue version with the specification.
