SKF
Mounted Bearings & Housings
SKF mounted bearings and housings are complete, pre-assembled bearing solutions that integrate a bearing, housing, sealing system, and lubricant into a single ready-to-mount unit. This product category eliminates the engineering complexity of designing separate bearing arrangements — the housing provides precise bearing alignment and support while sealing retains lubricant and excludes contamination. The SKF portfolio includes ball bearing units (insert bearings in pillow block, flanged, and take-up housings), roller bearing units (spherical roller bearings in robust cast iron housings), and the full range of SKF bearing housings (split pillow block, flanged, and take-up designs) that accommodate user-selected bearings. For OEMs manufacturing conveyors, fans, agricultural machinery, and processing equipment — and for maintenance teams replacing legacy mounted units — SKF mounted bearings and housings deliver consistent quality, dimensional interchangeability with industry-standard designs, and the reliability that comes from a globally trusted bearing manufacturer.

Complete, Ready-to-Mount Units Save Engineering Time
Each unit arrives factory-assembled, lubricated, sealed, and ready for immediate bolting to the machine frame — eliminating design time, component sourcing, and on-site assembly.
Wide Range of Housing Shapes & Materials
Choose pillow block (plummer block), square flanged, oval flanged, round flanged, and take-up housings in cast iron, pressed steel, composite polymer, and stainless steel.
Multiple Shaft Locking Methods
Select set screw locking (simple and economical), eccentric collar locking (for unidirectional rotation), SKF ConCentra locking (concentric, for high speeds and low vibration), or adapter sleeve mounting.
Ball Bearing Units for Moderate Loads & High Speeds
SKF ball bearing units with insert bearings handle radial loads and moderate axial loads across agricultural, HVAC, food processing, and light industrial applications.
Roller Bearing Units for Heavy-Duty Demands
SKF spherical roller bearing units in cast iron housings withstand heavy radial and axial loads, misalignment, and contamination in mining, cement, and material handling systems.
SKF Food Line & Corrosion-Resistant Options
Composite and stainless steel bearing units specifically designed for food and beverage washdown environments, offering chemical resistance and compliance with food safety standards.
Why Choose SKF Mounted Bearings Over Component-Level Assembly
Many equipment manufacturers and end users face a choice: design and assemble bearing arrangements from individual bearing, housing, seal, and lubrication components, or specify complete ready-to-mount units. SKF mounted bearings offer compelling advantages for applications where simplicity, speed of assembly, and field replacement are priorities. The factory-assembled unit ensures proper bearing fit within the housing, correct seal positioning, and optimal initial grease fill — quality factors that can be compromised during field assembly. For OEMs, complete units reduce inventory complexity (one part number instead of four or more) and assembly labor. For maintenance teams, ready-to-mount units minimize the skills and tools needed for bearing replacement, enabling faster repairs with less risk of installation errors.
SKF ConCentra Locking: The High-Speed, Low-Vibration Solution
Traditional set screw and eccentric collar locking methods, while economical, can cause shaft damage and may loosen under vibration or reversing loads. SKF ConCentra locking technology addresses these limitations with a concentric, self-centering design. The locking mechanism uses a multi-finger ring that wraps around the shaft and tightens uniformly as the locking screws are tightened, creating a 360-degree grip without the point-contact damage of set screws. This concentric fit eliminates the imbalance and vibration associated with eccentric locking methods, making ConCentra units suitable for high-speed applications such as fans, blowers, and pumps. The design also maintains shaft centering accuracy, which is critical for applications involving belts or chains where pulley alignment affects power transmission efficiency.
