It’s the famous Delta Quality built into each Delta Power Tool that makes the difference. hidden features, such as lubricated-for-life ball bearings, precision bored bearing seats, precision ground spindles, and dynamically balanced pulleys, guarantee that when you buy Delta — you buy the best.

Five Reasons for Delta Power Tool Superiority

1. Lubricated-For-Life Ball Bearings
   The bearing in Delta Power Tools are lubricated-for-life and completely sealed to keep out harmful dust, dirt and grit. This greatly reduces maintenance costs and assures you of long, trouble-free service for your power tool.
2. Precision Bored Bearing Seats
   Delta bearing seats are precision or “Diamond” bored. Result: the seat is absolutely smooth. The bearing fits closely, is tightly held and cannot loosen. With the seat perfectly round, true to size and in correct position, you get accurate, smooth and dependable bearing operation.
3. Preloaded Bearings
   The preloading of bearings in Delta Power Tools removes inherent “end play.” By so doing, the original accuracy of the machine is maintained over a longer period even when you usage puts excessive strain on bearing surfaces.
4. Precision Ground Spindles, Arbors, and Collars
   Delta precision grinds spindles, arbors and collars with an accurately controlled grinding wheel. This exact sizes of parts are maintained and extremely close tolerances are held between the arbor and inner bearing race — your assurance of full, even contact between arbor and bearing at all times.
5. Dynamically Balanced Pulleys
   A high-speed pulley not in perfect balance causes vibration which places a tremendous strain on the bearings. For this reason Delta high-speed pulleys are dynamically balanced on a sensitive balancing machine. A small amount of metal is removed where any unbalanced weight is indicated. This helps insure smooth, accurate performance of your Delta Power Tool.
