Y-bearing units consist of a housing, a deep groove ball bearing, seals or shields and grease. These ready to mount units are available in a variety of shapes and sizes. For additional information about these products, visit skf.com/bearings.
Some housing series are no longer available and are not listed in this catalogue. If replace - ment parts are required, especially for hous - ings in the SOFN or SDG series,
Our knowledge – your success:-
SKF Life Cycle Management is how we combine our technology platforms and advanced ser vices, and apply them at each stage of the asset life cycle, to help our customers to be more success ful, sustainable and profitable.
Our objective is to help our customers improve productivity, minimize main ten ance, achieve higher energy and resource efficiency, and optimize designs for long service life and reliability.
SKF can work with you to optimize current or new designs with proprietary 3-D mod ell ing software that can also be used as a virtual test rig to confirm the integrity of the design.
Innovative solutions Whether the application is linear or rotary or a combination, SKF engineers can work with you at each stage of the asset life cycle to improve machine performance by looking at the entire application. This approach doesn’t just focus on individual components like bearings or seals. It looks at the whole application to see how each com po nent interacts with each other.
SKF housings are typically made of either grey cast iron or spheroidal graphite cast iron. For information about the material options available for a particular housing type, refer to tables 1 to 4, starting on page 30, or the relevant product chapter. Grey cast iron Grey cast iron is the standard material for most SKF housings and is sufficient for the majority of applications. It is characterized by high strength, good damping capability and good thermal conductivity. Spheroidal graphite cast iron Spheroidal graphite cast iron contains graphite nodules, making it ductile. It therefore provides a higher degree of strength and toughness than grey cast iron. On average, housings made of spheroidal graphite cast iron can withstand 1,8 times heavier loads compared to housings made of grey cast iron.
When selecting a housing, many factors should be considered. The selection process depends not only on the bearing type and size but also on the ability of the housing to safely accommodate the magnitude and characteristics of all applied loads. Beside this, important considerations are mounting, maintenance, sealing options and bearing lubricant requirements. Search for a housing To identify housings that are suitable for a specific bearing type, size and shaft-bearing combination, use the Bearing index, starting on page 742, or the online application SKF Housing Select, available at skf.com/housings. Also keep in mind that a roller bearing unit may be the preferred solution († table 5). An online search facility for bearing units is also available at skf.com/housings.

Adjust the bearing selection If there is no suitable housing for the selected bearing type or size, consider switching to a bearing that can be accommodated in a standard housing. The result will be a more costeffective bearing/housing solution. Select the final housing variant Once a housing has been selected, be sure that the housing and available sealing solutions will accommodate the loads, shaft-bearing combination, lubrication method and operating conditions, e.g. type and level of contaminants. Consider all housing variants, including those with a non-standard seat tolerance or special seals. For unique requirements, contact the SKF application engineering service.
SKF housings are intended for both interior and exterior applications. The following corrosivity categories, in accordance with ISO 12944-2, are applicable for SKF housings: • C2 for all housings except SE and SED plummer (pillow) block housings • C3 for SE and SED plummer (pillow) block housings Additional information about corrosivity categories is provided in table 6. Custom painting / corrosivity category The standard colour and corrosivity category of an SKF housing is indicated in the relevant product chapter. SKF housings can also be supplied in other colours and/or corrosivity categories († table 6) or according to customer specifications. Housings that have a non-standard painting requirement are identified by the designation suffix P followed by a unique twoor three-digit number e.g. SNL 510-608/P76. If a housing is going to be repainted, SKF recommends taking the following precautions prior to painting: • Cover all housing openings. For housings with seal grooves, place discs cut from cardboard or plastic in the seal grooves. This is particularly important because residual chemicals or abrasives from the preparation process can lead to premature bearing and seal damage. • Remove all grease fittings and protect all threaded holes with plugs. • To avoid any chemical attack of the surface when washing painted castings, follow the instructions from the supplier of the washing chemicals regarding concentration, temperature, and time. The paint is resistant to commonly used low alkalescent washing chemicals.
