Susceptibility to Water Damage
Phenolic wheels are vulnerable when their outer shell is chipped or cracked, especially if exposed to water. Water can seep into the wheel, causing it to expand and warp, leading to uneven weight distribution and making the wheel difficult to push. This damage may eventually result in the complete failure of the wheel.
Potential Floor Damage
Due to their extremely hard tread, phenolic caster wheels can pick up debris during use. This debris can harden on the wheel’s surface, leading to dents and dimples on flooring. Phenolic wheels are best suited for clean, solid concrete surfaces. When used on rough floors, they may sustain scratches and other damage, which can then be transferred to the floor.
Noise Issues
Phenolic caster wheels aren’t the quietest, especially when debris builds up on the tread. This can cause increased friction and vibration, leading to higher noise levels. However, they are generally quieter than steel or aluminum wheels.
Lightweight and Durable
Phenolic caster wheels are lightweight due to their composition of phenolic resin and macerated canvas. Despite this, they are strong enough to handle heavy stationary loads.
Resistance to Chemicals
Phenolic wheels are resistant to oil, grease, and some liquids, provided the outer shell remains intact. However, if the shell cracks, the wheel becomes vulnerable to liquid infiltration, which can cause severe damage.
Ideal for Infrequent Use
Phenolic caster wheels are a cost-effective choice for applications where they won’t be in constant motion. Their durability makes them suitable for heavy, stationary loads, but they perform best on flat, clean surfaces. Improper use or exposure to rough conditions can lead to debris buildup and increased noise output.
