Since one bearing can be used with different bearing seats, one bearing housing can also be used with different types of bearings. Therefore, there are many varieties of bearing housings. However, the same bearing housing models are not exactly the same in different company samples. For different applications of standard bearing housings, housings with different materials such as grey cast iron, ductile iron and cast steel, stainless steel, plastic special housings are available.
According to the different requirements of the bearing and the bearing housing, the classification of the bearing housing is not completely the same. When using it, it should be carefully checked according to the design.
Classified by bearing housing shape
The bearing housing is divided into: split bearing housing, sliding bearing housing, rolling bearing housing, flanged bearing housing, and outer spherical bearing housing.
The outer spherical bearing is also called the bearing unit, such as square flange bearing units. When there is no bearing, it is called an outer spherical bearing. The outer spherical bearing housing is divided into 200 series, 500 series, 300 series, 600 series, XOO series according to the series of bearings.
Integral (non-separable) vertical housing base, bearing housing with screw fastening. These vertical housing blocks were originally developed as axle boxes for light rail trucks, but can also be used with conventional vertical housing sets. Non-separate vertical housing blocks are more rigid than split housings and some can withstand heavier loads. The outer spherical bearing housing also belongs to the integral seat.
As an intimate partner of the bearing, the bearing housing plays an important role in the entire shafting. It is generally located at both ends of the shaft, and its main function is to support and fix the bearing so that the shaft and its connecting parts have a certain positional relationship. In addition, the bearing housing is typically provided with a seal to reduce bearing contamination.
Bearing housing FAQ
Wear is the most common problem with housings, and bearing block wear often occurs.
The conventional method generally uses post-weld machining to repair, and the surfacing causes the surface of the component to reach a very high temperature, causing deformation or cracking of the component, and the downtime is greatly prolonged by machining to obtain the size. The use of polymer composite materials for on-site repair has no thermal influence, and the thickness of repair is not limited. The wear resistance of the product and the concession of metal materials are not guaranteed, ensuring 100% contact and repair of the repaired parts, reducing equipment. Shock shocks to avoid the possibility of wear. On-site repair to avoid machining methods.
Generally only four steps are required: 1. Surface treatment, it is necessary to repair the surface of the steel casting pillow block bearing to remove oil and moisture; 2. Reconcile and repair materials; 3, the material is applied, the material is evenly applied to the repaired part of the bearing seat, and the filling is strong; 4. Wait for the material to solidify, and heat the surface of the material to accelerate the curing of the material.
The general bearing chamber wear can be repaired in 3-6 hours. The operation is simple and easy to learn. No special equipment and special training are required. Compared with laser welding and cold welding, it saves time and effort. The cost is only 1/5 of the general repair cost. 1/10, on-site repair is to reduce equipment repair time and transportation costs.
