INA, a brand within the Schaeffler Group, manufactures a variety of housing bearings designed to provide support and secure mounting for bearings in various applications. These housing units are typically made of cast iron, cast steel, or pressed steel and are equipped with bearings and sealing elements to protect against contamination and ensure reliable operation. Here are some common types of INA housing bearings:
Plummer Block Housings (Pillow Blocks): Plummer block housings, also known as pillow blocks, are robust housings that provide support and secure mounting for bearings. They typically feature a base with mounting holes, a housing with a bore for the bearing, and end covers or seals to protect against contaminants. Plummer block housings are commonly used in conveyor systems, agricultural machinery, and industrial equipment.
Flanged Housings: Flanged housings have an integral flange that provides a mounting surface for the bearing. They are used in applications where space is limited or where the bearing needs to be axially retained. Flanged housings are commonly used in conveyor rollers, machine tool spindles, and material handling equipment.
Take-Up Housings: Take-up housings are designed to accommodate bearings that require axial adjustment, such as spherical roller bearings with adapter sleeves or ball bearings with set screws. They typically feature a sliding mechanism or adjustment screw to facilitate easy adjustment of the bearing position. Take-up housings are commonly used in conveyor systems, agricultural machinery, and industrial equipment.
Split Plummer Block Housings: Split Plummer block housings consist of two halves that are split along the horizontal or vertical plane, allowing for easy installation and maintenance of bearings. They are used in applications where access to the bearing is limited or where shaft alignment is critical. Split Plummer block housings are commonly used in large industrial equipment such as paper mills, steel mills, and mining machinery.
Pressed Steel Housings: Pressed steel housings are lightweight and economical housings made of stamped or pressed steel. They are commonly used in light-duty applications such as electric motors, household appliances, and small machinery where space and cost are considerations.
Corrosion-Resistant Housings: INA offers corrosion-resistant housing units made of stainless steel or special coatings to protect against corrosion in harsh environments. These housing units are commonly used in food processing equipment, chemical plants, and marine applications where corrosion resistance is critical.
These are some of the main types of INA housing bearings available, each designed to meet specific application requirements and provide reliable support and mounting for bearings in various industrial environments.
