48Q074 - Walter 608-2Z Replacement Ball Bearing for Power Tools

Precision Replacement Component

The Walter 48Q074 Ball Bearing is a high-quality replacement component designed to restore the functionality of Walter Surface Technologies power tools. Identified by the industry-standard designation 608 2Z and manufactured in accordance with DIN 625 specifications, this deep groove ball bearing is engineered for precision, durability, and high-speed performance. It serves as a critical mechanical interface, facilitating smooth rotational motion while supporting radial and axial loads within the tool's assembly.

The "608" classification denotes its specific dimensions: an 8mm inner diameter, a 22mm outer diameter, and a 7mm width. These dimensions make it one of the most versatile and widely used bearing sizes in compact industrial machinery and power tools. The "2Z" suffix indicates that the bearing is equipped with metal shields on both sides. These non-contact shields are essential for preventing the ingress of dust, metal shavings, and other particulate matter common in grinding and finishing environments, while also retaining the pre-filled grease lubricant inside the race.

Using genuine OEM parts like the 48Q074 ensures that the replacement fits perfectly without play or misalignment, which is crucial for maintaining the balance of high-RPM tools like angle grinders and sanders. Improper bearings can lead to excessive heat generation, noise, and premature failure of the tool's motor or gear assembly. This bearing is pre-lubricated for life, requiring no additional maintenance upon installation.

Technical Specifications

This bearing is constructed from high-grade hardened steel to withstand the stresses of continuous industrial use. The DIN 625 standard ensures consistent tolerances and clearance classes, providing reliable operation under varying thermal conditions. Whether used in the armature, spindle, or fan assembly of a Walter tool, this component delivers the smooth operation required for precision surface finishing tasks.
