Identification details & limits

Reference identifier: GDNB / GDSB / FB-507 / GDEB. Compare each listed detail with the exact product and the source document. Do not submit a personal serial number or access code to this website.

Identification and scope details from the cited sources; each row retains its source locator.
GDNB center-support bushingThe supplier describes a 1-inch nylon bushing with a 2-inch outside diameter, supplied as one unit for center-support use.
GDSB steel bearingThe source describes a 1-inch steel bearing with a 2-inch outside diameter, supplied as one unit.
GDSB supplier ratingThe listing states 400 lb at 35,000 cycles for doors up to 12 feet high. This is a supplier rating, not an independently tested system capacity.
FB-507 football bearingThe title associates FB-507 with a Raynor side-bracket bearing. The description states galvanized steel, a 1-inch inside diameter and 3-3/8-inch hole-to-hole spacing, supplied as one unit.
GDEB flange pairThe listing describes left and right end-bearing flange plates with 12-gauge galvanized steel and pressed-in 1-inch Freeway bearings.
GDEB offset limitThe setup text gives a shaft-offset value of 3-3/8 without an explicit unit. Image-only dimensions have not been reviewed.
Matching boundaryThese items serve different support and mounting roles. A shared 1-inch label or outside diameter does not establish interchangeability or fitment for a particular door.
Identity and provenanceRetain the complete supplier-listed labels. The Raynor association and OEM wording do not independently prove the manufacturer of every item.
