SNR Plummer block housings and mounting accessories
SNR Plummer block housings is a module which contains the following components:
1.SNR Plummer block housing
made of cast iron or special materials,2-parts or compact,that can be screwed onto the mounting surface with bolts, all kinds of bearing housings are made for all applications where high performance is needed,XRB offers a wide range of different SNR Bearing housings,all offered type are the best choice regarding design,quality and life time.
2.one or several bearing,which is mounted either directly onto the shaft or which are attached with the aid of an adapter sleeve.
3.a sealing system to protect the bearing in service
4.a device for re-lubrication of the spherical roller bearing & deep groove ball bearings under running conditions.
SNR plummer block housings design is available in two basic versions:
1.as a 2-parts plummer block housings with an integrated self-aligning or spherical roller bearing
2.as a compact unit with an integrated self-aligning or spherical roller bearing,but also with a bearing or a combination of several other bearings
Along with this fundamental classification,the SNR Plummer block housing are also differentiated in terms of plummer block housings,suspended housing,double or triple bearing housing and flange plummer block housings
SNR Plummer block housing are made of grey cast iron as standard,for special applications spheroidal cast iron or cast steel in various qualities are also available.similarly,various steel materials as well as other application-specific materials can be used. for special requirements it is also possible to coat the housing surfaces,in such cases please ask us for specific delivery options. all SNR Plummer block housing are painted in blue(RAL7031 and RAL5010 for series SD),All externally-located surfaces are painted,i.e. including the underside and in part- the housing's bolting surface.special paintings are also available on request.
the bearing seat and all other internally-located surfaces are preserved. for oil lubricated bearing housing the SNR plummer block housing's free interior surfaces are painted.the bearing seat fittings in the individual housings are geared towards each individual application. basically however,it is always selected such that axial displacement of the bearing outer race in a floating bearing is possible.
Bearing with cylindrical bores are mounted directly onto the shaft, a shaft fit is to be selected that matches the applications and bearings used,the bearing itself must however be firmly mounted onto shaft,an SNR induction heating device should be used to mount the bearings,cylindrical bearing require a shaft shoulder as a contact surface within the housing,this in turn means that the diameter of the inlet or outlet bore in the housing generally deviates from the diameter of the bearing used.the figure below shows a double SNR Plummer block housing ZLG300, bearing with tapered bore are mounted onto the shaft with the aid of an adapter sleeve.here the tolerance of the shaft maybe higher than for bearings with a cylindrical bore.fundamentally,bright drawn shafts may be used. the bearing ring is fastened onto the sleeve by clamping it axially, in doing so the radial bearing clearance after mounting must be adhered to.
