May Insider: Tips & Insights for NTN’s SPAW/SPW Bearing Units

Welcome to our May edition of the NTN e-newsletter!

This month, we’re excited to share some valuable insights and tips on our SPAW bearing units, designed to enhance your operations and ensure optimal performance.

SPAW Bearing Units: Features and Benefits

Our SPAW bearing units are engineered to withstand high shock and impact, making them ideal for demanding environments. Here are some key features:

  • Sturdy Ductile Iron Housing: One-piece design for superior durability.
  • Versatile Snap Ring: Allows for flexible (fixed or float) positioning.
  • Spring-Loaded, Single-Lip Heavy Contact Bearing Seal: Ensures excellent sealing and noise reduction.
  • Unitized Bearing Insert: Facilitates easy replacement.
  • Phosphate-Coated Locknut/Adapter Sleeve: Provides secure mounting and corrosion protection.
  • 60% Faster Install Time: Our 6 components versus our competitors’ 24, allows for faster and easier installation.

Available in both inch (SPAW) and metric (SPW) sizes, our bearing units cater to various applications:

  • Inch Sizes: 1 15/16” – 5 1/2” bore sizes, available as 2-bolt, 4-bolt, or solid base.
  • Metric Sizes: 50mm – 140mm bore sizes, available as 2-bolt or solid base.

Interchange Guide

Our SPAW/SPW units share the same base-to-shaft-center height and bolt position as SAF/SN units, ensuring seamless interchangeability. This simplifies the transition and enhances compatibility with existing setups.

Installation Tips for SPAW Bearings

  1. Inspect the Shaft: Ensure it’s clean and free from burrs or damage.
  2. Position the Adapter Sleeve: Center the tapered part within the bearing.
  3. Install the Lock Washer and Nut: Hand-tighten and verify positive contact.
  4. Set the Internal Clearance: Follow recommended torque settings.
  5. Secure the Housing: Mount the unit securely to minimize misalignment.
  6. Lubrication: Factory greased.  Consider NTN Single Point Lubricator too.
  7. Superior Protection: Use optional external end covers in contaminated environments.
