251CALR | Live Roller Cam Adjusted Heavy Duty Conveyor

Roach 251CALR is the choice to horizontally convey heavier unit loads where transfers, side loading or unloading is required. Its standard center drive allows for reversible operation.

Specifications

TREAD ROLLERS: 2-1/2″ dia. x 11 ga. steel, model 251S.

PRESSURE ROLLERS: 1.9″ dia. x 16 ga. steel, model 196S; same BF as conveyor up to 39″ BF; units 43″ BF and above, rollers are 21″ BF with
STANDARD 12″ wide belt; 27″ BF if OPTIONAL 24″ belt is used.

BELTING: 12″ wide PVC-120.

RETURN ROLLERS: 1.9″ dia. x 16 ga. steel, model 196S

CENTER DRIVE: Reversible drive with 24″ integral belt take-up. For units under 8′-0″ overall length, drive components must be stacked.

END PULLEY: 4″ dia. with 1-3/16″ dia. shaft on 15″-39″ BF; 6″ dia. with 1-7/16″ dia. shaft above 39″ BF; both crowned.

DRIVE PULLEY: 8″ dia. with 1-7/16″ dia. shaft on 15″-39″ BF; 12″ dia. with 1-15/16″ dia. shaft above 39″ BF; both crowned and fully lagged.

SPEED: 35 FPM, constant.

BEARINGS: All pulley bearings are precision, heavy duty, lubricated, ball bearing units with cast iron housings.

BED: 7″ x 1-1/2″ x 10 ga. formed steel channel frame slotted for tread rollers to pop-out. When unit is installed at 7′-0″ elevation or higher, rollers must be retained in conveyor frame. Specify desired elevation. Bed sections attached with couplings and floor supports.

MOTOR DRIVE: 1 HP, 230/460/3, 60 cycle, ODP right angle gear motor.

FLOOR SUPPORTS: 8″ and 12″ center drive (with 4″ or 6″end pulley) adjustable 33″ to 36″ TOR with SH-6 at end plates and SH-7 at intermediates. Supports provided on 5′ centers and should be lagged to floor.

ROLLER CHAIN: Drive pulley is driven by No. 50 roller chain for 1-1/2 HP or less and No. 60 chain on larger drives. Chain take-up provided on motor base.

ELECTRICAL CONTROLS: Optional
