Heating a bearing expands it for precise placement and alignment on the shaft without damage. Pressing (driving) a cold bearing onto a shaft can cause it to misalign – as little as a 0.001" difference can reduce a bearing's lifespan by 50%. Bearing heaters generate clean, even heat for precision placement, resulting in extended bearing life. Heating alternatives such as hot oil baths and torches are messy and dangerous. Torches and element tops create uneven heat and expansion and cause hot spots that can change the metallurgical properties of the bearing steel.
