Coach Peter de Villiers defended his decision not to make more wholesale changes against a Namibia side they should rout.
"We have to manage our players sensibly if we want to have 30 players fit when we get to the proper tough games," de Villiers said.
"Managing the players and changing the team every week is two things. I said I'm going to manage the players. I didn't say that every week everybody else would play. Along the line we'll have to manage [captain] John [Smit], too."
Smit has appeared in all six of their tests this year, the starting hooker in five of them.
With Victor Matfield still out injured, Smit will earn his 109th cap for South Africa to move ahead of Matfield and become the Springboks' sole appearance record-holder.
Van der Linde is in for Jannie du Plessis and Alberts replaces Heinrich Brussow in the only changes in the forwards.
Hougaard, who takes over from Fourie du Preez, will start for the Springboks for the first time since the loss to Scotland last November.
Back on the wings are Bryan Habana and Gio Aplon, replacing JP Pietersen and Odwa Ndungane.
In the reserves, Chiliboy Ralepelle is included in a match 22 for the first time for Bismarck du Plessis, who has been rested.
Habana has recovered from a knee injury against Wales.
De Villiers said Habana was not picked because he'd have an easier shot at claiming the Springboks' test tries record to himself. With 38 tries, he shares it with the long-retired Joost van der Westhuizen.
"Bryan brings some energy to the team. He's a bundle of energy. I'm glad to give him a run again," de Villiers said. "If you can give me one player on this team who will put his interests above the interests of the team, then today I will personally send him home. If he gets his record-breaking try and we lose the game, what does it mean to the team, and what does it mean at all to be here?"
Injured locks Matfield (hamstring) and Johann Muller (hamstring), first five-eighths Butch James (hip) and centre Jean de Villiers (rib) weren't available.
Namibia have made six changes - five in the forward pack.
Bertus O'Callaghan has been swapped with Hugo Horn at hooker for his first start in the tournament following the 49-12 loss to Samoa last week, and tighthead prop Marius Visser will make his first appearance in the Cup, with Raoul Larson dropping out of the 22.
Tinus du Plessis returns to the blindside flank, moving Jacques Nieuwenhuis back to No 8 at the expense of PJ van Lill and restoring the same loose trio that played Fiji in their cup opener.
Standout captain Jacques Burger said that after conceding 49 points each to Fiji and Samoa, Namibia still had more to offer.
"Hopefully you've not seen the best of us. Hopefully we can do better than we've done in our previous two games," he said. "I do believe we've got a lot of good players in our team and we can do a lot better. "I really believe in my team and we can give South Africa a good show."
The teams have met only once, in 2007, and the Springboks won the World Cup warmup 105-13. Namibia still have 10 survivors in tomorrow's 22 from that match in Cape Town, including du Plessis.
"It's going to be awesome. South Africa are our neighbours, so it's a bit of a grudge match," du Plessis said. "We played them in 2007 and it didn't go so well. We were just young guys coming out of club rugby."
