Stainless Steel Clamp Head

Stainless Steel Clamp Head Material and Structural Design

Stainless steel clamp heads are precision fastening components used to secure guardrails, side rails, and sensor brackets to conveyor framework. Each unit consists of a two-piece split body, a clamping screw, and a base mounting flange. The split-body design allows installation onto existing tubing or profiles without disassembly of the mounted component.

Two material grades are available. SUS304 stainless steel contains a minimum of 18% chromium and 8% nickel, providing corrosion resistance for indoor industrial and general washdown environments. SUS316 stainless steel adds 2% to 3% molybdenum, which improves resistance to chloride-containing solutions such as saltwater, chlorinated cleaners, and food processing sanitizers. All clamp bodies are investment cast and then machined to dimensional tolerances of ±0.1 mm on clamping bores.

The clamping mechanism uses a stainless steel socket head cap screw that compresses the split body around the inserted tube or shaft. When tightened to the specified torque of 8 Nm to 12 Nm (depending on tube diameter), the clamp maintains positional hold under conveyor vibration loads. The base flange features slotted mounting holes for angular adjustment during installation.

Conveyor Clamp Head Dimensions and Specification Range

The clamp head series covers multiple tube diameter sizes and base mounting patterns to match different conveyor guardrail systems. Standard clamping diameters include 12 mm, 16 mm, 20 mm, 25 mm, and 30 mm round tubing. Base mounting options include single-hole pivot bases, two-hole fixed bases, and T-slot compatible bases for aluminum extrusion frames. All dimensions are produced to ISO 2768 medium tolerance class.

Guardrail Bracket Installation and Compatibility Notes

Clamp heads install using standard hex key or socket wrench tools. For round guardrail tubing, the clamp can be rotated to any angle before tightening, allowing alignment with conveyor side rails of varying heights. The split-body design also permits retrofitting onto pre-installed cable bundles or tubing runs without disconnecting terminated ends.

For aluminum profile conveyor frames, the clamp base mounts directly into standard T-slots using drop-in T-nuts. For stainless steel welded frames, the base bolts through pre-drilled holes with matching stainless steel nuts and washers. To prevent galvanic corrosion when mounting to aluminum, optional insulating washers are available.

Stainless Steel Clamp Industrial Application Scenarios

Food and Beverage Conveyor Lines

In food and beverage production facilities, SUS316 clamp heads secure side guides and hold-down rails on bottle filling lines, canning systems, and packaging conveyors. The smooth cast surface resists bacterial buildup and withstands daily high-pressure washdown cycles with alkaline or chlorine-based cleaners.

Pharmaceutical and Hygienic Conveying

Pharmaceutical packaging lines and medical device assembly conveyors use stainless steel clamp heads for guardrail mounting where cleanroom-compatible materials are required. The non-porous stainless steel surface supports wipe-down sanitization protocols and does not shed particulate matter.

Outdoor and Corrosive Environment Logistics

Outdoor conveyor systems, port side material handling lines, and coastal warehouse installations use SUS316 clamp heads to resist salt spray and atmospheric corrosion. The all-stainless construction avoids the rust staining that occurs with carbon steel or zinc-plated components in coastal environments.

FAQ About Stainless Steel Clamp Heads

What is the difference between SUS304 and SUS316 clamp heads?

SUS304 provides general corrosion resistance for indoor industrial use. SUS316 contains molybdenum and performs better in chloride-exposed environments such as salt spray, marine settings, and chlorinated washdowns. For most indoor conveyor applications, SUS304 is sufficient.

Can these clamps be used on square tubing?

Standard clamp heads are designed for round tubing. Square or rectangular profile clamping requires a different jaw geometry. Custom square-bore versions are available on request for specific profile dimensions.

What is the maximum recommended operating temperature?

Stainless steel clamp heads maintain structural properties from -20°C up to 200°C. Continuous operation above 120°C may reduce the effective clamping force due to thermal expansion differences, and torque should be rechecked after temperature cycling.

Are custom hole patterns or special finishes available?

Custom base hole patterns, polished surface finishes (Ra ≤ 0.8 μm for hygienic applications), and laser-etched part numbers can be specified for volume orders. Minimum order quantities apply to custom configurations.
