Description
SKF SNL 3256 G belongs to split plummer block housing, part of our Bearing housings range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for SNL 3256 G and any equivalents.
A cast iron split housing from SKF, the SNL line accepts bearings with either a tapered or a cylindrical seat. Because the housing separates, the bearing can be fitted or pulled without taking the transmission apart, which suits horizontal shaft equipment such as conveyors, mills, pumps and fans. MR Industrial Accessories LLC supplies this line to plants in the United States and Latin America.
Reading the code helps when you order. SNL marks the split housing family, the digits that follow set the size and the load it can carry, and the trailing letter such as G points to a sealing or configuration variant. Sizes climb through the range: SNL 3134 G, SNL 3138 G and SNL 3180 G sit at one end, while SNL 3248 G and SNL 3256 G are the largest of the group. Every code stands for one specific assembly, so confirm it against the bearing you plan to mount.
These housings turn up on belt conveyors, bucket elevators, mixers, flour mills and pumping equipment, and also in aggregate processing plants, sugar mills and dairy facilities. Where the shaft is already in place or the surrounding space is tight, the split design is what makes the difference: the bearing comes out on its own, without disturbing the rest of the drive.
Selection comes down to three things: shaft diameter, bearing type (spherical roller, ball and so on) and the conditions on site. Sealing deserves attention, since dusty or damp areas call for the right labyrinth or seal. At assembly, check that shaft and seat are aligned and lubricate for the speed and temperature of the duty. Bolts drawn down evenly keep the housing from distorting, which would work against bearing life.
Housings built to the same dimensional standard can be swapped between brands. On a replacement, compare center height, hole spacing and seat diameter; codes differ from one maker to another, but cross-referencing the original usually turns up an equivalent. If you only have measurements or the marking on the old housing, we can identify the part for you.
For a quote, send the full code, for example SNL 3134 G, or a photo of the housing in service, through WhatsApp or email. We can also advise on the bearing and the mounting accessories that go with it, and suggest equivalents when a code is not immediately clear.

Frequently asked questions
- What does SNL mean on a split housing?
- SNL is the SKF designation for this cast iron split housing line. The digits after it give the size and capacity, and a final letter such as G signals a sealing or configuration variant. Confirm the full code against the bearing you intend to mount.
- How do I pick the right SNL housing?
- Start with the shaft diameter and the bearing type, then look at where the unit runs. Dust or moisture will steer you toward a particular seal, and alignment plus correct lubrication matter just as much. If anything is unclear, send us the shaft measurements and the load.
- Do SNL housings from different brands interchange?
- Housings made to the same dimensional standard generally do. For a replacement, check center height, hole spacing and seat diameter. From the code or the measurements we can help you locate the equivalent.
