Bolted flange units are bolted roller bearing units with 4 bolt holes and are square. They can be used in applications where there is sufficient space for housing units and provide adequate installation security for high-load applications. Flanged housing units are used when the bearing mounting surface is perpendicular to the shaft axis. Typically, insert bearings can be adjusted or aligned within the housing to accommodate long shafts. Most manufacturers offer flanged units in two series: imperial and metric. Flange unit materials include cast iron, thermoplastic, glass-filled PBT polyester, stainless steel and other metals. Plastic housing units require little to no maintenance and are protected from rust and corrosion, but they may not be suitable for high temperature applications. Bolted roller bearings also offer different functions. The housing unit may include a grease fitting to add lubricant to the sides or a slinger for dust protection. Flanged housing units are set screw locking, sleeve collar or eccentric locking collar locking for one directional application. These housing units are available with bearing inserts in a variety of materials and seal types. Chromium steel bearings are lubricable and are usually paired with cast iron units. Designed for use in wet or harsh environments, UHMW-PE bearings are self-lubricating and can be used with most metal housings. Bearings are the first choice for lighter applications and continuous lubrication. Depending on the manufacturer, stainless steel, nickel and galvanized are also available. Inner ring width depends on the required load capacity; narrower inner rings are better for light duty applications. In the 300°F to 500°F range, exotic seals, greases, bearing fits, clearances and housings are required, potentially eliminating many of the associated purchases by using HT series bearings, especially in bearing inserts ( PI-HT), installation, installation and maintenance costs associated with these applications, require no lubrication, retrofit into existing housings, and have an operating temperature range of 600°F, these bearing products are bakery, paving Economical, simple answers to questions and applications in the processing industry. Mounted bearings and mounted ball bearing units provide much needed support and stability. Whether you need housings or flanged bearings, these models can be bolted to a variety of surfaces for ease of use.
