Bearing assemblies

The 100 Series and 300 Series Bearing Assemblies are designed for use in gypsum board and ceiling tile continuous dryers. These self-aligning, bearing assemblies with carbon-graphite replaceable bearing cartridges are used to hold the powered rollers in large continuous dryers that are used for curing gypsum board and ceiling tile. The 100 Series and the 300 Series bearing assemblies are designed to permit the bearing cartridge to be replaced quickly and easily even after years of exposure to the high temperatures inside the dryer. Fast and easy bearing cartridge replacement is required in these dryers because of the short down time allowed for these large, high production dryers. The Metcar 100 Series bearing assemblies are designed to enable fast bearing cartridge replacement from the axial direction (that is when the bearing cartridge can slid over the end of the shaft). The 100 Series Bearing Cartridge slides onto the end of shaft, ears on the bearing cartridge flange slide into slots in the housing, the cartridge is rotated ninety degrees, and a circular clip lock is used to block the slots so the cartridge is secured in the housing The Metcar 300 Series bearing assemblies are designed to enable fast bearing cartridge replacement from the radial direction. This is necessary when the bearing assembly is located behind the roller drive sprocket or behind locking collars so it is not possible to slide the bearing cartridge over the shaft. The bottom half of the 300 Series Split Bearing Cartridge slides under the shaft and a slot on the bearing cartridge flange engages with a stud in the housing. The top half of the 300 Series split bearing cartridge is placed over the shaft and an “easy clip” wire spring is used to hold both halves of the split cartridge in place.
