About cylindrical bearings
A cylindrical roller bearing is a type of bearing that contains cylindrical rolling elements. The name cylindrical bearing comes from these elements. Compare it to ball bearings where the elements are balls. Cylindrical bearings are available in different sizes and in different materials and qualities. Cylinder bearings are used in various applications.
Operation
The operation of a cylindrical roller bearing is simple: there is a solid inner ring and a solid outer ring and they roll over each other by means of long, cylindrical elements. If a cage is used, the cylindrical elements do not touch each other. This design enables a very high speed.
Most important features
Cylindrical roller bearings are very stiff, have a high radial load capacity and, as mentioned, the cage version is suitable for higher speeds. Full bearings are less suitable for this. Separate mounting of inner and outer rings makes assembly easier. Cylindrical bearings are available in single-row, double- or multi-row variants.
Types
Cylinder bearings without cages can withstand high loads because they contain many rolling elements. However, this type is less suitable for higher speeds. For such applications it is better to opt for a one- or two-row variant. Both types are excellently resistant to radial forces. There are also high-precision bearings of two- or multi-row variants. You can also opt for bearings with reinforced roller sets and solid brass cages.
Brands
We supply cylindrical bearings from ISB, CBS, SKF, FAG, GRW, DV-B and many other brands.
Single row cylindrical roller bearings
Single-row cylindrical roller bearings, which are often equipped with a brass cage, have a solid outer and inner ring. The cylindrical rolling elements are located in the cage. There are variants with track collars on the inner and outer rings. Depending on this, the bearings are available as a loose bearing, support bearing or fixed bearing.
In addition to brass, the cage is also available in glass fiber reinforced polyamide, indicated with the suffixes P and TVH for SKF and FAG cylindrical bearings respectively. Cages are also available in sheet steel (suffix J). The brass cage is indicated with the suffix M for these brands.
Precision bearings
We supply cylindrical bearings where very high precision is required. We also call these super-precision cylindrical roller bearings. They are double-row precision bearings that are used, for example, in machine tools. They allow bearings of main spindles in radial direction that are very stiff and extremely precise.
The precision bearings consist of an outer ring, inner ring with track collars and two rows of cylindrical rollers, guided by solid brass cages. For optimal adjustment of the radial bearing play, the inner ring has a conical bore. It is possible to disassemble the bearings, which makes assembly easier.
Full cylindrical roller bearings
Full cylindrical roller bearings consist of a solid outer and inner ring. Between the outer and inner ring are the rolling elements that are guided between the track collars of the rings.
Full cylindrical roller bearings with snap ring groovesFull cylindrical roller bearings are also available with snap ring grooves. These are double row bearings and fixed bearings. These bearings also have a high stiffness and can withstand very high radial forces and axial forces in both directions. The solid outer and inner ring are also provided with track collars. The bearings are equipped with sealing rings on both sides. Grooves are provided in the outer ring of the bearing, making it suitable for mounting retaining rings.
Delivery
We have stocks of various commonly used cylindrical bearings. When we have bearings in stock, you can have them delivered the next day. We send shipments every day via our carrier GLS. For reasons of reliability, we do not send shipments as letterbox mail.
In case of great urgency, you can also pick up your order from us in Capelle a/d IJssel. Our opening hours are Monday to Friday from 8:30 AM to 5:30 PM.
Ask for advice
Which type of bearing is most suitable for your application? Is a bearing with or without cage most suitable? Should the bearing contain one, two or more rows of rolling elements? Is it wise to use bearings of the highest quality – and therefore cost – or should it be a cheaper bearing? What running accuracy is desired and what tolerances can be taken into account? We are happy to help you with these and other questions regarding cylindrical bearings.
