Cylindrical Roller Bearings SKF NUP210 ECP
The SKF NUP210 ECP cylindrical roller bearing, measuring 50x90x20 mm, is a single-row fixed bearing designed for high radial loads.
The NUP210 ECP cylindrical roller bearing is a single-row roller bearing with an optimised internal design in the SKF Explorer series. With a bore of 50 mm, an outside diameter of 90 mm and a width of 20 mm, it is suitable for demanding industrial applications. The open bearing features a lightweight polyamide cage and operates with standard radial clearance. Thanks to its fixed bearing design, it absorbs radial forces whilst simultaneously securing the shaft axially on both sides.
What is the NUP210 ECP cylindrical roller bearing suitable for in industrial applications?
This fixed bearing is used where high radial loads occur and shafts must be guided unambiguously in the axial direction. Thanks to two fixed flanges on the outer ring and a fixed flange with a loose flange disc on the inner ring, the NUP design limits axial play in both directions. Typical applications include mechanical drives and shaft mountings where precise guidance under radial loads is required.
What does the NUP design with a polyamide cage mean when selecting a bearing?
When designing the system, take into account the thermal and operational conditions. The polyamide cage promotes low-friction operation and allows for a temperature range of -30 to +120 degrees Celsius. Dimensional accuracy corresponds to class P0/PN (ABEC 1), whilst running accuracy of P6 (ABEC 3) offers a tighter concentricity tolerance. As this is an unsealed bearing without a lubrication bore in the outer ring, an external housing seal and a targeted lubricant supply are required.
What are the dimensions of the NUP210 ECP cylindrical roller bearing?
With an internal diameter of 50 mm, an external diameter of 90 mm and a width of 20 mm, this roller bearing complies with standardised key dimensions. This enables it to be fitted into precisely matched shaft seats and corresponding bearing housings in mechanical and plant engineering.
How does the NUP design differ from other cylindrical roller bearings?
Unlike free-running bearings such as NU or N, the NUP design functions as a fully-fledged fixed bearing. It has fixed flanges on both bearing rings and a loose flange disc on the inner ring. As a result, the bearing supports not only high radial forces but also axial forces from both directions within the shaft system.
What is the purpose of the polyamide cage in this roller bearing?
The polyamide material reduces the weight of the cage and minimises friction and noise during rotation. At the same time, the elastic material dampens the acceleration forces acting on the roller elements. The permissible temperature range for this cage variant is between -30 and +120 degrees Celsius.
What is the bearing clearance and tolerance class of the bearing?
This model features a standard radial bearing clearance, designed for conventional fits and standard operating temperatures. The dimensional tolerance corresponds to the basic class P0 or ABEC 1. The higher running accuracy of class P6 or ABEC 3 ensures particularly smooth running.
What should be borne in mind when lubricating an open bearing?
As the bearing is manufactured without integrated seals, the lubricant must be supplied via the surrounding machine housing. Depending on the speed and design, either grease or lubricating oil may be used. An external seal at the bearing location prevents the ingress of dirt and the loss of lubricant.
What makes the Explorer version from SKF stand out?
SKF’s Explorer range features cylindrical roller bearings with an optimised internal geometry. An adapted contact geometry between the cylindrical rollers and raceways helps to reduce edge stresses and improve load distribution during operation. This promotes high load-carrying capacity under demanding radial operating conditions.
