LongDescription#@#NA#@@#Cleaning Instructions#@#Unplug wheel assemblies before cleaning. Remove visible debris and scrape away grease. Apply a degreaser or mild detergent, scrub with a nylon brush, rinse with water, and dry with a lint-free cloth. Inspect bearings and stem for wear; lubricate with food-grade oil if needed. Clean surrounding floor and cart frames to prevent grime buildup and reduce fire risk. Follow CSA and local health rules to protect customers and pass inspections.#@@#Additional Info#@#Thunder Group PLCB4140 4" stem caster installs on bus carts PLBC3316 and PLBC4019, rated at 1.05 pounds each; the stem design ensures secure mounting, and the swivel action allows reliable maneuverability.#@@#General Info#@#Description #@#

Installers will appreciate the straightforward stem fit and consistent dimensions that simplify fleet maintenance and replacement planning.
#@@# Diameter Match#@#
Choose this 4-inch diameter caster when you need stable rolling across tile, vinyl, or sealed concrete. Engineers specify 4-inch wheels to balance load distribution and reduce rolling resistance, improving push-force metrics during peak service.
#@@# Stem Attachment#@#
Use the standard stem design to install directly into existing bus cart sockets without welding or complex adapters. Technicians save time during swaps because the stem seats securely and aligns to maintain caster orientation under lateral loads.
#@@# Load Handling#@#
Rely on a robust construction that supports repeated loading cycles common in dining halls and hospitals. Operators experience fewer wheel failures over service rotations, which lowers parts consumption and reduces unscheduled downtime.
#@@# Brake Option#@#
Note that this configuration ships without brakes to suit carts that require uninhibited movement for staging and transport. Managers can select locked units separately where stationary restraint becomes necessary for unloading or serving operations.
#@@# Weight Specification#@#
Expect a unit weight of approximately 1.05 pounds, which keeps replacement parts affordable to stock and minimizes added mass to carts when retrofitting multiple positions. Procurement teams can calculate shipping and inventory costs accurately using that figure.
#@@# Compliance Note#@#
Specify CSA-recognized components when facility standards demand third-party validation; consult local codes to verify acceptance for food service and institutional applications.
#@@#Delivery Details#@#

Remove carts from service and clean mounting stems with a degreasing solvent; dry thoroughly before reinstallation. Lubricate swivel bearings and wheel bearings every three months with food-grade lubricant to reduce friction and extend service life. Verify brake engagement and replace any worn components immediately. Torque mounting fasteners to manufacturer specifications and document maintenance actions for compliance and traceability.
