What the AI looks for in Bearing Hinges
- Hinge size for door thickness
- 4-1/2 inch hinges for 1-3/4 inch doors up to about 36 inches wide; 3-1/2 inch hinges for 1-3/8 inch residential doors An undersized hinge on a thick, heavy door sags and wears the bearings early.
- Hinge count
- Three hinges for doors up to about 90 inches tall, plus one more for each additional 30 inches Too few hinges lets the door rack and bind at the latch side.
- Weight class
- Standard weight for normal use; heavy weight for high-frequency doors, doors with closers or wide doors Closers and heavy traffic wear out standard bearings and knuckles.
- Bearing count and grade
- Look for ball bearing hinges certified to BHMA A156.1 grade for commercial use Certified grades are tested for cycle life, which plain marketing claims are not.
- Corner radius
- Match square, 1/4-inch or 5/8-inch radius corners to the existing mortise A mismatched corner will not seat in the existing mortise without chiselling or filling.
Brands that matter
