The High Temperature Cam Followers with suffix HT4/G – Gravity up to (450°C) & L/2 (-60°C) are specialized guide bearings designed for extremely high and low temperature environments. The product features are described as follows.

Product Overview

HT4/G (Gravity): Extreme High-temperature version up to 450°C
L/2: version designed to operate at temperatures as low as -60°C (even -73°C depending on configuration)
All suitable for medium-heavy loads and low speeds (120–280 rpm).

Main structure & technology

High-temperature resistant version HT4/G – Gravity

Lubricant: Special grease containing MoS₂ (molybdenum disulphide) creates a stable lubricating layer at very high temperatures.
Manganese phosphate coating (according to EN ISO 9717): ensures increased protection against corrosion, good adhesion of lubricants and smoother running
Material: Chrome steel
Effectiveness: Stable work in furnaces, heat treatment lines, and hot steel production.

Low temperature version (L/2)

Lubricant: Special grease that does not solidify at -60°C to -73°C.
Material: stainless steel (SUS304, AISI440C / 9CR18Mo)

The suffix HT4/G – Gravity and L/2 series are commonly used in the following:

High temperature:

Industrial kiln trolley
Hot rolling steel line
Glass factory – heat treatment
Kiln/drying oven conveyor

Low temperature:

Cold storage conveyor belts
Freezing line
Cryogenic device

Popular Series & Product Codes with inch size

CF series: (stud-type cam follower)
CYR series: (yoke-type / heavy-duty)

Optional: Inch sizes, custom OEM designer signature

Important technical notes:

Do not use standard bearings as replacements, as the lubricant will burn or solidify.
It is necessary to determine the following:
- Load (kN)
- speed (rpm)
- Mounting type (stud / yoke)
With temperatures up to a maximum of 300°C, further testing is recommended:
- material expansion
- assembly tolerance
