Sealmaster® Material Handling Mounted Ball Bearings

Product catalog summary
Overview: The document outlines the specifications and features of Sealmaster Material Handling Mounted Ball Bearings, emphasizing their construction, locking mechanisms, and optional components. These bearings are tailored for material handling applications and come in various configurations to meet diverse requirements.
Specifications: The bearings are constructed with cast iron housings and feature an extended inner race insert with a ball riding nylon retainer. They include a contact seal and a black oxide treated flinger to resist contaminants and reduce friction. Available in standard industry bore sizes and housing configurations, these bearings are versatile for different applications.
Locking Mechanisms: Two main locking options are provided: setscrew locking, which reduces inner ring distortion and vibration, and the Skwezloc® concentric locking collar, which offers near-perfect concentricity, minimizing shaft damage and vibration.
Optional Components: An optional snap-on end cap is available for safety, adhering to OSHA standards. Although the bearings are sealed for life, they can be relubricated if necessary, with a standard lubrication fitting included.
Features and Benefits: Notable features include a positive contact molded nitrile rubber seal, an anti-rotation rivet to prevent outer ring creep, and a zone-hardened inner race for enhanced lock reliability. The solid cast iron base provides stability and resistance to shock and vibration.
Product Variants: The document describes various bearing series, such as the NPMH Series (Standard Duty Pillow Block with Setscrew Locking), TBMH Series (Tapped Base Pillow Block with Setscrew Locking), and SFMH Series (Standard Duty 4-Bolt Flange with Setscrew Locking), each available in different bore sizes and dynamic ratings.
Technical Details: Detailed dimensions, bolt sizes, and weight specifications are provided for each bearing type, along with part numbers for easy identification and ordering.
MH Series Overview: The document also covers the MH Series Standard Duty Insert Bearings, focusing on the Setscrew Locking and Skwezloc Locking Collar mechanisms. It includes detailed dimensions, weight, and other critical parameters for each bearing type.
Specifications:
  • Duty: Standard
  • Rolling Elements: Ball
  • Locking Mechanism: Setscrew Locking or Skwezloc Locking Collar
  • Seal Type: Contact Seal and Flinger
  • Temperature Range: -20° to 200°F
Dimensions and Weight:
  • Each bearing is listed with its bore diameter, part number, and dimensions in both inches and millimeters.
  • Maximum radial clearance and setscrew or Torx cap screw specifications are provided.
  • Unit weight is given in both pounds and kilograms.
Key Features:
  • The document highlights the use of ball rolling elements and the standard duty classification.
  • It emphasizes the importance of the locking mechanism, either setscrew or Skwezloc, for secure installation.
  • Contact seals and flingers are used to protect the bearings from contaminants.

Material Handling Bearings Features and Benefits Multiple Locking Methods Skwezloc® Concentric Locking Collar SKWEZLOC is a concentric locking collar clamp design that results in nearperfect concentricity of the shaft to the bearing bore and maintains near perfect ball path roundness, while reducing fretting corrosion. This design eliminates the shaft damage of setscrew locking, and minimizes bearing induced vibration for smoother quieter operation. The collar has a TORX head cap screw that outlasts stripping 12 times longer than hex head cap screws. Setscrew Locking 120° spaced, balanced three...

Material Handling Bearings Features and Benefits continued Anti-Rotation Rivet An Anti-rotation rivet prevents outer ring creep, or rotation, within the housing. Zone Hardened Inner Race Sealmaster incorporates a unique heat treat process that hardened the inner race only where it is needed...under the ball path. The zone hardened inner race results in improved lock reliability as a result of less distortion at setscrew location and improved thread conformity resulting in improved clamping and resistance to setscrew back-out. Solid Cast Iron Base Solid bases are standard on Sealmaster Material...
