Pillow block split bearing housing,is the upper cover and base of the seat can be separated, mainly bear radial loads.Suitable for cylindrical and tapered hole self-aligning roller bearings and self-aligning ball bearings. This type of bearing seat is mainly used in metallurgy, mining, conveying systems, environmental protection equipment, and so on. The main models include SN series, SD series, SNU series, SNL series, 1500, 1600 series, Z2500Y, Z2600Y series, GZ2, GZ4 series. The main difference between each series is the load they bear and the sealing form (wool felt, double lip seal, U-shaped seal, labyrinth seal, etc.). It has good thermal conductivity, easy installation and disassembly, and greatly improves the effectiveness of the seal.
In use, there is no need to design a separate bearing box, so the size is small, the structure is simple, and it is easy to use. The bearing seat is a monolithic structure with high load-bearing capacity, good rigidity, and interchangeability. It has automatic heart adjustment function.

Maintenance and upkeep of pillow block split bearing housing
(1) The use of bearing seat cooling system. When used correctly, the cooling water for the bearing seat not only extends its service life, but also improves production efficiency. When using cooling water for the bearing seat, the use of release agents can be greatly reduced. Its benefits lie in saving die-casting cycles, improving product quality, reducing mold sticking, pulling, and aluminum sticking. It can also reduce the loss of the top rod and core caused by overheating of the bearing seat temperature.
(2) The bearing seat must be preheated during the production process to prevent the occurrence of cracks caused by sudden contact with hot metal liquid in the cold bearing seat.
(3) Clean the parting surface of the bearing seat. The operator should thoroughly clean the parting surface of the bearing seat with kerosene, which not only prevents the bearing seat from being squeezed, but also, after cleaning, can open up the exhaust groove blocked by residual release agent or other dirt.
(4) If the bearing seat is equipped with neutron control, it is absolutely forbidden for the signal line between the die-casting machine and the bearing seat to have a joint phenomenon. The reason is very clear. In daily production, it is difficult to avoid the signal line getting wet or the joint wrapping being easily broken, which can cause a short circuit with the machine tool.
