NTN SN split plummer block housings accommodate a bearing arrangement. The divided body is part of their physical identification, but a housing reference does not replace the designation of the bearing inside. This line differs from NTN insert-bearing units: an SN housing inquiry must describe the assembly contents separately. Do not assume the housing code includes a bearing, sleeve, seals and all retaining elements.

SN506, SN507 and SN508 share SN and have different numeric blocks. Their progression distinguishes catalog references; it does not automatically calculate base dimensions, height or fastening distances. Copy the code from the housing or drawing and compare it with the installation geometry. If only part of the marking remains, state which portion is readable. Do not record a number seen on the inner bearing as though it were the housing number.
For a support mounted on a machine bed, document the seating surface, fixing points and shaft position relative to the base. On process equipment or a conveyor, also show neighboring components and the side through which the shaft passes. The housing provides an interface with the structure, while bearing and accessories define another part of the assembly. If the problem concerns the base or cap, identify the repair scope before deciding which assembly needs quoting.
Send MR Accesorios Industriales the SN code, base and fixing measurements, shaft height, housing photographs and application. Add documented bearing and sleeve codes and the number of positions being repaired. An open-housing view can help identify components if maintenance has already dismantled it. Do not turn measurements estimated from photographs into confirmed values: distinguish measured data from drawing information.
It identifies the housing in this line. Specify the bearing and other elements when defining the request.
It does not describe the entire housing. Base, fixing points, height and the accommodated bearing reference are also required.
Send its marking and photographs plus information about the retained base. Review must consider both housing parts together.

NTN SN500 and SN600 series housings are split plummer blocks: the housing opens into two halves so the bearing can be mounted and inspected without removing the shaft from the machine. They hold self-aligning ball bearings and spherical roller bearings with a tapered bore, mounted on the shaft with an adapter sleeve. MR Accesorios Industriales, in Buenos Aires, Argentina, is an official NTN distributor.
Just the manufacturer part number is enough: we will quote it and provide dimensions and equivalents via WhatsApp or email.
