ForewordSNR is one of Europe's leading manufacturers ofrolling bearings and has been one of the industry'sbiggest innovators for decades. Our innovationsin rolling bearing technology for the automotive,aerospace and industrial sectors are the basis forour consistent growth. Our integration into theRenault-Nissan Group is a further guarantee of highproductivity and quality.Contact with our customers and their application isespecially important to us.A closely meshed network of sales offices and tradepartners allows us to maintain direct contact at alltimes - worldwide.In terms of new product development, this customerfocus means that our customers can directlyinfluence our products. Our guiding principle is towork together to find constructive solutions.Product quality, efficiency and high utility for usersare the basis for strategic partnership between SNRand you - our customers.SNR bearing housings are an established elementof our product strategy and, in conjunction with ourPREMIER rolling bearings, provide a unique level ofperformance.Find out for yourself.2
The SNC bearing housing conceptVariable, efficient, user friendly! That's the basic concept behind our SNC series.Basic designOur two-part bearing housings are made up of an upper and a lower section. This greatly simplifies mountingand maintenance of the units, as the bearing and sealing elements can be mounted on the shaft first andthen simply inserted into the pre-positioned lower section of the housing.These units are compatible with ISO standards 02, 03, 22, 23 and 32 sized self-aligning bearings or rollerbearings. The high performance SNR PREMIER self-aligning roller bearings offer huge additionalbenefits in terms of service life and running behaviour. Our application engineers will be happy to advise youon the design and dimensioning of your beari ng locations.A wide variety of different sealing systems ensures that optimum solutions are available for all kinds of applications,from the less stringent requirements for a bearing location under clean ambient conditions throughto usage under extremely adverse conditions.Unique design selling points, such as the circular ribbing on the housing allow fault-free operation even athigh temperatures and with heavy loads. The optimum vibration behaviour of our FEM-optimised housingsextends their service life considerably.Increased housing rigidity and improved heat dissipation are further advantages of the SNC series.Other design details are described in more detail later in this catalogue.Complete systemsSNR enables its customers to order application-specific complete systems. These include bearing units thatare supplied fully assembled with the shaft and pre-lubricated for direct installation.This results in economic benefits such as:• Reduction of logistics costs: One supplier - one responsibility• Reduction of commissioning costs due to avoidance of mounting errors• Reduction of manufacturing costs due to elimination of the need to mount individual componentsseparately• Reduction of inventory costsModular principleThe versatility and the number of variations in the SNC housing series ensure that a wide range of modulesare available, with even the standard options offering enormous variety. This means that complex andexpensive special designs can often be avoided. The modular principle, with its different dimensions,sealing elements and rolling bearing variations, provides a wide range of options that offers a technicallyand economically viable solution for most applications.3
